Not able to add links (internal server error)

Permalink
Hello,

I hope somebody can help me. I am the administrator of the websitehttp://www.tc-neufeld.at. I really like concrete5 but I never was able to add links to my site. It doesn't matter if I link to another page or to a subpage. The following error occurs:

"Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, tc-neufeld@gmx.at and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log."

I couldn't find anybody with the same problem. Thank you very much for helping me!

Is this when you trying to add the link? Or after you click on the link?

Thanks for your reply. The error occurs when I try to add the link as soon as I want to save.

You're running an updated version. Please check your config/site.php and see if the following line is there:
<?php define('DIRNAME_APP_UPDATED', 'concrete5.6.1.2');?>

If it isn't, add it and check if it works.
