In conjunction with the failed installation of an extension (yag), the install tool is no longer available with the following error message:
PHP Fatal error: Class '\\tx_install_session' not found in /var/typo3_src-6.0.2/typo3/sysext/core/Classes/Utility/GeneralUtility.php on line 4158
Any suggestions are welcome.
Ok, I'm one step further.
Assuming the backend login works, it helps to clear the cache via the flash button.
Which leads me to the question: Is there a way to do this in the shell in case the BE login is broken?
Remove/comment the bad extension in the LocalConfiguration.php file and then remove content of /typo3temp/Cache/ directory.
It will allow you restore to the state before the malformed installation.

I got to work on a Typo3 page and I have to say I'm at the very beginning if it comes to TYPO3.
So I wanted to fix a bug and updated the plugin "fluidpages" from version 4.1.0 (I guess) to 4.3. That cause the "Oops, an error occurred!" in the backend and frontend, so I dont have access from that side. I still have the FTP login for the website. The version of TYPO3 is 8.7.18.
The errorcode I get is that one:
Could not analyse class:
"FluidTYPO3\Flux\Configuration\ConfigurationManager" maybe not loaded
or no autoloader?
Class FluidTYPO3\Flux\Configuration\ConfigurationManager does not exist
So does anyone know what I need to do?
From my research I think I need to update another plugins to make it back to work? And can I update them just by uploading them through FTP?
Thanks in advance!
Edit: After I tried to get the old version of the plugin running, I'm getting this error code from the log file:
Mon, 17 Feb 2020 22:59:56 +0100 [ALERT] request="fec23f8baf6dc" component="TYPO3.CMS.Frontend.ContentObject.Exception.ProductionExceptionHandler": Oops, an error occurred! Code: 2020021722595594039a4d - {"exception":"TYPO3\CMS\Extbase\Mvc\Exception: The default controller for extension \"Flux\" and plugin \"Page\" can not be determined. Please check for TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin() in your ext_localconf.php.
You can enter the Install Tool via https://example.org/typo3/install.php and start with Check for broken extensions. If that doesn't yield the extension in question, you can always manually change the PackageStates.php file and remove the extension you want to unload. Afterwards you should flush all caches through the Install Tool.
In the long term you should consider a few things:
Use a local development environment which mirrors your production environment. You can safely perform all steps without any risk here before deploying.
Use a deployment strategy/tool which allows for rollbacks. This allows you to quickly revert to a working version of your instance in case all other checks have failed. A simple but flexible solution is Deployer, you'll need SSH for this though.
Have you tried dumping autoload from Install Tool? Generally, it would help for the class not loaded problem. Otherwise, you may want to check the log at typo3/temp/var/log/ and find the errors in code.
I'm currently running TYPO3 version 8.7.18 and running a site_package that was made by using the site package builder: link
Whenever I try to add a form by using the default backend forms module I get the default message Oops, an error occurred! along with that the following error
TYPO3\CMS\Form\Domain\Configuration\FormDefinition\Converters\AddHmacDataConverter not found
Searching for the issue I get several hits on the Gitlab but these do not provide any solution.
Along with this setup, I've added the forms module as a static include in my top-level template.
do you have a composer installation or an extension manager build up?
If a class is not found you may need to rebuild the autoloader information.
My error turned out to be caused by a corrupt installation. I've had to upload the file AddHmacDataConverter.php in the following path /public_html/typo3/sysext/form/Classes/Domain/Configuration/FormDefinition/Converters. A very weird error indeed.
For those that came here with the same error, make sure to check that folder. Apart from that add the news as a static inclusion in your top domain. You could also follow #Bernd Wilke's idea which s to disable the extension, clear all system caches (and additionally remove typo3/temp/autoload and then active the extension again.
I am getting below error in magento 2 local system:
We're sorry, an error has occurred while generating this email.
It is not showing me the sample data installed in catalog. Please help me out to get solution of this problem.

The first thing you need to do is go to your .htaccess file. Uncomment
SetEnv MAGE_MODE developer
The error message is 90% of the time misleading and most likely you have an xml parsing issue. Either way turning on the developer environment and clearing the cache will pull the error.
Without seeing your error log it'd be hard to give an exact diagnosis. Some users will say sendmail will fix this error but generally this is because the error is trying to be emailed to you and that is because you are not in the correct developing environment to debug the issue. This could be because you are in default or production mode which is not ideal for fixing issue.
The sendmail module is meant to allow a site to operate and if any issues do occur with the site then the developer can be notified and hopefully the error hasn't caused a full site rendering issue. This way a site can still operate unbeknown to users and the issue can be resolved by a qualified developer behind the scenes.
This error is quite misleading. In my case an error in MySql query was causing this.
You should enable developer mode the get the exact error.
php ./bin/magento deploy:mode:set developer
In My case issue get solved by giving permissions to directory pub/media/catalog/product/
Enable developer mode using command line php bin/magento deploy:mode:set developer
Clear cache using command line php bin/magento cache:flush
Reload the frontend page
After reloading the page the message will change to
Error filtering template: Unable to write file into directory \C:/xampp/htdocs/Magento/pub/media/catalog/product\cache\f073062f50e48eb0f0998593e568d857/m/b. Access forbidden.
Follow this link to fix Magento 2: Unable to write file into directory. Access forbidden
Clear cache
Reload the frontend page again
If you see another message after enabling developer mode you can search for it
In my case it was missing php-gd extension on my machine.
This was on my exception log (magento_root/var/log/exception.log):
main.CRITICAL: exception 'Exception' with message 'Required PHP extension 'gd' was not loaded.' in /var/www/html/magento2/vendor/magento/framework/Image/Adapter/Gd2.php:620
Solved by installing php-gd library on my Ubuntu machine with the following command:
sudo apt-get install php-gd
If you want to install for php5.6 then you may run:
sudo apt-get install php5.6-gd
This can be for any error occurred in the page. The notice is different. The notice is given when system tries to send error email to administrator and failed while in Production mode.
For actual error one should enable developer mode and enable display error in app/bootstrap.php and checking error logs. It can be any error like php or mysql.
ini_set('display_errors', 1);
Thanks
Please check your /var/log/exception.log
This is issue raised because your product does not upload. so check your database or upload your sample database again .Let me know what error in exception.log
Fatal error: Class 'Raveinfosys_Exporter_Helper_Data' not found in ..\app\Mage.php on line 546.
I have installed new new extension Bulk Import+Export Orders to CSV in Magento 1.7, but I am getting above fatal error in admin. Any help is appreciated.
I struggled with this error in this extension for quite some time when I figured out the solution (for me, at least). Disable compilation in System > Tools > Compilation. Once you disable compilation, install the extension, clear the Magento cache (I left the cache page opened in another tab to make sure I had access to it) and you should see an "Exporter" tab in the header. Hope this solves your issue because it took me many hours to find the problem.
I've updated my Typo3 from 4.5.5 to 4.7.0 and I get several deprecated errors:
ERROR: Content Element type "login" has no rendering definition!
call to undefined error in t3lib_div::view_array
fail to include class.t3lib_htmlmail.php
The install tool gives me "typo3/ext/ directory not writable" but I've the correct right. I've even allow all?????
When I select a CType Element in the BE it give me this warning: PHP Warning
PHP Warning: Invalid argument supplied for foreach() in /var/www/typo3_src-4.7.0/t3lib/l10n/parser/class.t3lib_l10n_parser_llphp.php line 95
The solution for 2. is to use the new class t3lib_utility_debug but what is with the other errors?
Edit: 1. http://lists.typo3.org/pipermail/typo3-english/2011-November/078129.html
Edit 2: The solution for the missing class t3lib_htmlmail is to include another class t3lib_mail_message: require_once(PATH_t3lib .'mail/class.t3lib_mail_message.php');
You solved allready: install system extension "felogin"
you solved allready: use t3lib_utility_debug
check where the error is from. Often it is helpfull to search for that file in typo3conf/temp_*.
You could check your filesystem, if your webserver is allowed to write to typo3/ext/. I guess, it is not. But you do not need to. Usually you install extensions to typo3conf/ext/.
Update your language files via the extension manager.
Well, i know it is to late now, but for all others wo think about an update: just activate the deprecation log in the isntall toll and fix that problems first!
Updating from 4.5.X to 4.7.x broke my felogin as well. The reason was that there has been a local extension installation that has been of higher priority than the system one. So if you suffer the same update issue, check for an local installation of felogin in "typo3conf/ext" - and delete it in case it is there. This solved my problem!
