undefined function TYPO3\CMS\IndexedSearch\mb_strcut() - typo3

I'm trying to create a webpage using TYPO3 8.7, but when i go to Localhost/index.php it says "Oops an error has occured".
The only way i can see my webpage, is through the TYPO3 backend login apperently.
This is the error that it logs in the backend of TYPO3:
>
Core: Exception handler (WEB): Uncaught TYPO3 Exception: Call to undefined >function TYPO3\CMS\IndexedSearch\mb_strcut() | Error thrown in file >/var/www/html/typo3_src-8.7.0/typo3/sysext/indexed_search/Classes/Indexer.php in >line 1314. Requested URL: Localhost/index.php
And my line 1314 is this:
$bodyDescription = mb_strcut($bodyDescription, 0, $maxL, 'utf-8');
I'm very new to this. So far i've been able to sort all bugs with the help from these forums and others, but unfortunately I can't find any solution to this one.
Any help is greatly appreciated.
Let me know if i need to provide some additionel information.

This error means that mbstring php extension is not enabled. You should install it, if you have Ubuntu you should execute
sudo apt-get install php-mbstring

How do I enable Error Reporting in TYPO3?

I have made a contact form but upon submitting it I get the error: Oops, an error occurred! Code: 201905310232036dfcc153.
I would like to get more information so I can start debugging. So my question is: How do I enable error reporting in TYPO3?
You have to add this line in your TypoScript
config.contentObjectExceptionHandler = 0
After setting to 0, you will see detailed errors in frontend when an exception
is thrown.
To reset it, simply delete the lin or set to 1.
here is a blog post from me about it (in German): https://www.naderio.de/oops-an-error-occurred-komplette-fehlermeldung-anzeigen/
In the directory typo3temp/var/logs/ there should be a file named typo3_somehash.log. Search this file for the error code.
Go to Install Tool and configure SYS|displayErrors = 1
This enables the debug exception handler and you will get a stacktrace instead oops an error occurred.
You can also write it directly in your typo3conf/AdditionalConfiguration.php or typo3conf/LocalConfiguration.php:
$GLOBALS['TYPO3_CONF_VARS'][SYS]['displayErrors'] = 1;

TYPO3 Upgrade Wizard Fails on DatabaseRowsUpdateWizard

i updated a project from TYPO3 7.6 to ^8 by following the official guide. latest steps were the composer update. i removed extensions/packages not compatible with ^8 and updated the ones available for ^8. im able to reach the install tool, the TYPO3 admin backend and the frontend (with errors).
so i ended up at the step were i should use the upgrade wizards provided by the install tool. i completed a few wizards without any issues but then faces a pretty one - first i tried to run DatabaseRowsUpdateWizard within the install tool but that failed with a memory error - i tried the cli approach with
php -d memory_limit=-1 vendor/bin/typo3cms upgrade:wizard DatabaseRowsUpdateWizard
the processing worked but it ended up with following error:
[ Helhum\Typo3Console\Mvc\Cli\FailedSubProcessCommandException ]
#1485130941: Executing command "upgrade:subprocess" failed (exit code: "1")
thrown in file vendor/helhum/typo3-console/Classes/Install/Upgrade/UpgradeHandling.php
in line 284
the command initially failed is:
'/usr/bin/php7.2' 'vendor/bin/typo3cms' 'upgrade:subprocess' '--command' 'executeWizard' '--arguments' 'a:3:{i:0;s:24:"DatabaseRowsUpdateWizard";i:1;a:0:{}i:2;b:0;}'
and here is the subprocess exception:
[ Sub-process exception: TYPO3\CMS\Core\Resource\Exception\InvalidPathException ]
#1320286857: File ../disclaimer_de.html is not valid (".." and "//" is not allowed in path).
thrown in file typo3/sysext/core/Classes/Resource/Driver/AbstractHierarchicalFilesystemDriver.php
in line 71
im pretty much lost and dont know were to start to get this fixed - help is much appreciated
Issues like these usually stem from broken URLs in RTE fields as can be seen in the error output:
File ../disclaimer_de.html is not valid (".." and "//" is not allowed in path)
In this case you should manually prepare the database and run SQL statements which replace the broken/obsolete ../ prefix from all affected records. An example query:
UPDATE tt_content
SET bodytext = REPLACE(bodytext, 'href="../', 'href="')
WHERE bodytext LIKE '%href="../';
Notice that this query is very basic and can destroy your data, so make sure you run some SELECT statements first to make sure nothing breaks. Also keep a backup of your database at hand.
Sometime, custom or TER extension also have RTE such as tt_news where you might come across same issue. To fix that, you just need to run the same query with the according table.

PHP startup error using CodeIgniter 3

I am getting tbe following error intermittently on my website
A PHP Error was encountered
Severity: Core Warning
Message: PHP Startup: Invalid library (appears to be a Zend Extension, try loading using zend_extension=opcache.so from php.ini)
Filename: Unknown
Line Number: 0
Backtrace:
I am using LAMP with PHP7 and the CodeIgniter installation is standard. The error has no file nor line to investigate, but my host ensures me that the server is correctly configured.
What could be causing this? I cannot even find a reference to opcache in the CodeIgniter 3 source code. (application files are very basic MVC brochureware stuff, so it's nothing the app has added)

Empty pagetree in TYPO3 7.2 backend

I am setting up a web portal using TYPO3 version 7.2. I successfully installed TYPO3 following this article on a Red Hat 4.8.2-16 machine. Everything worked fine and I created some pages until for some reason the pagetree didn't show any content any more. So now the backend looks like this http://goo.gl/3p0uQn
My browsers debug console only returns this error:
TypeError: TYPO3ViewportInstance.DebugConsole is null backend.php:79:5
but I have no idea if this is related to the empty pagetree.
This occurs on Firefox, Chrome and IE, so I guess it has nothing to do with the browser.
Also, I am logged in as an admin so it should not be due to wrong access rights.
Does anybody know what's going on there?
UPDATE:
The TYPO3 Log gives me some PHP Warnings
Core: Error handler (BE): PHP Warning: Cannot modify header information - headers already sent in /var/www/typo3_src-7.2.0/typo3/sysext/core/Classes/Http/AjaxRequestHandler.php line 255

UPDATE 2
Meanwhile I installed 7.2 completely fresh (even with a new database) and I still get an empty pagetree. I also tried 6.2 LTS, but also here, no pagetree. I'm beginning to think that there is a problem with my PHP settings. Im using PHP 5.6.9 and MariaDB 10.0.19.
Try tu put that on your php.ini :
always_populate_raw_post_data = -1
It worked for me.
Have a nice day.

You have a PHP error somewhere. Please check your webserver log or php log for error messages. You can also show the error messages by choosing the development preset in the Install Tool or by setting the context environment variable to Development.
Make sure to clear the cache via Install Tool at least once (Important Actions).
