Error 404 not correct work - web-config

I have some problem with work web-page 404.
Error 404 to the second level of links works fine, but when typing a link above the 3rd level (see screenshot), the web page is not displayed correctly.
For example enter link description here
The settings were made through the hosting panel by simply turning on and indicating the 404 error page.
The support team answers that this is a problem on the part of the developer.

How to findout more about 404 error from Github pages?

I have created a simple web page on GitHub and here is the url. I am now using fiddler to load it, and every time I load the page, I get a 404 error as well as a successful connection and download of the page, and I do not know why I get the 404 error. When I am logged into GitHub, and click on the clone button of my repo, the url is: https://github.com/InfosecureIT/InfosecureIT.github.io.git
How can I know what file the GitHub server is referring to when it says file can not be found?
# jpvillaisaza - Sure, the error is 404 file not found. is a picture, which would describe the error better.
The error you're getting is related to a missing favicon.ico file. Even though your HTML code doesn't specify a favicon, browsers can request it and display an error. This shouldn't be a problem with loading everything else, but you might want to either add a favicon picture, which will probably be better for your site, or find a way to avoid the favicon request (see How to prevent favicon.ico requests?, for example).

Custom tab shows up blank (no content) with the words "I'm a Teapot"

I recently created a Facebook custom tab for a organization page and followed all the developer's instructions. I have a secure site, made sure all the dimensions are correct, etc.
For some reason, the tab shows up completely blank, no content. Sometimes it simply has the words "I am a teapot", which I found out was an error code...What does this error mean and how do I fix it???
See, your actual url to the application that is hosted on some domain, should be SSL certified.
Eg: If your url was http://my-app.com, then https://my-app.com must also work, else it will not be published to the facebook!

URLs redirect to spyware site

We are developing an app that makes posts on behalf of our users to Facebook. Within those posts, we want to put links to external (non-Facebook) websites.
Looking at the links in the status bar of the browser (usually Chrome), the correct URL is displayed. However, Facebook seems to wrap the actually-clicked link into some extra bells-and-whistles. Usually, this works correctly.
Sometimes, however, this URL wrapping ends up sending the click to a URL like:
http: //spywaresite.info/0/go.php?sid=2
(added space to make it non-browsable!) which generates Chromes severe warning message:
This happens very occasionally on Chrome, but very much more often in the iOS browser on the iPhone.
Does anyone have any pointers as to how to deal with this?
EDIT
For example, the URLs we put in the link is
http://www.example.com/some/full/path/somewhere
but the URL that actually gets clicked is:
http://platform.ak.fbcdn.net/www/app_full_proxy.php?app=374274329267054&v=1&size=z&cksum=fc1c17ed464a92bc53caae79e5413481&src=http%3A%2F%2Fwww.example.com%2Fsome%2Ffull%2Fpath%2Fsomewhere
There seems to be some JavaScript goodness in the page that unscrambles that and usually redirects correctly.
EDIT2
The links above are put on the image and the blue text to the right of the image in the screenshot below.
Mousing over the links (or the image) in the browser shows the correct link. Right-clicking on the link and selecting "Copy Link Address" gets the fbcdn.net link above (or one like it). Actually clicking on the link seems to set off some JavaScript processing of the fbcdn.net link into the right one... but sometimes that processing fails.
I'm not 100% sure what you're asking here, but i'll tell you what I know:- are you referring to this screen on Facebook?
(or rather, the variation of that screen which doesn't allow clickthrough?)
If you manually send a user to facebook.com/l.php?u=something they'll always see that message - it's a measure to prevent an open redirector
if your users are submitting such links, including the l.php link, you'll need to extract the destination URL (in the 'u' parameter)
If you're seeing the l.php URLs come back from the API this is probably a bug.
If links clicked on facebook.com end up on the screen it's because facebook have detected the link as suspicious (e.g. for URL redirector sites - the screen will allow clickthrough but warn the user first) or malicious/spammy (will not allow clickthrough)
In your app you won't be able to post links to the latter (an error will come back saying the URL is blocked), and the former may throw a captcha sometimes (if you're using the Feed dialog, this should be transparent to the app code, the user will enter the captcha and the dialog will return as normal)
If this isn't exactly what you were asking about please clarify and i'll update my answer
Rather than add to the question, I thought I'd put more details here.
It looks like the Facebook mention in the original title was mis-directed, so I've removed it.
We still haven't got to the bottom of the issue.
However, we used both Wireshark and Fiddler to look at the HTTP traffic between the Chrome browser (on the PC) and Facebook. Both showed that Facebook was returning the correct URL refresh.
Here's what Wireshark showed:
What we saw on Fiddler was that our server is issuing a redirect to the spywaresite.info site:
We are working with our ISP to figure out what is happening here.

URL unreachable without error

I've updated my site with OG meta information, but it's not working perfectly. On this portal some article is unreachable for Facebook (Comments say about it). But when I paste URL in FB status, it can't load initial image and teaser for this article. This problem is not permanent, but too often to make me sad. Clicking on the link takes me to the developers.facebook.com/tools/lint? page, and can't say any error, everything seems to be fine. What can I do, can anybody help me?
Some URLs for checking (clicking on the debug page the error message disappear, and everything will be fine):
http://www.femcafe.hu/cikkek/celeb/jessica-simpson-2-millio-dollaros-szulese
http://www.femcafe.hu/cikkek/celeb/nem-haragszom-markra-interju-eden-kiraval
If you need more URLs, I can send more.
The new link for lint is :
http://developers.facebook.com/tools/debug
Make sure you don't have any redirects on your pages/links, it will scrape the last/final url.
Check if you have any cache issues etc.
I don't see any errors

Facebook linter returns “Error parsing input URL” although most info shows up if FB button is activated

I’m trying to troubleshoot a specific behavior. The last entry I wrote on a WordPress blog returns no data when run through Facebook’s Object Debugger (linter). I just get a “Error Parsing URL:Error parsing input URL, no data was scraped.”
However, if I try with any previous post, all seems to be fine: the linter scrape the page correctly;
If the Facebook button under the problematic entry is clicked, a snippet is correctly produced, except for a thumbnail of the image: permalink, summary, all is correct.
When I examined the source code of for the permalink entry in my browser, I can see all tags correctly displayed, even the og:image tag (the URL is valid).
This is sudden behavior. I didn’t experience any problem since I setup Facebook Open Graph protocol on my blog.
P.
Got it. Sometime between the time I created my previous entry and the time I wrote the new one, the CDN (content delivery network) I’m running me blog through stopped working.
Facebook linter wasn’t happy because it couldn’t find the image (since the image wasn’t distributed through the CDN: the CDN handles media, not plain text, that’s why Facebook was still able to scrape title, summary, etc.).
Lesson learned: when running test with Facebook Object Debugger, first disable any cache system (or make sure it works properly) or it may impact the results.
