I`m using vb 3.8.1 pl 1 on a VPS with php 5.2.10 and MySQL 5.0.67
what should I do?

This is most likely caused by a modification. Try posting a new post (not Quick Reply), and you should see the error, correct?

Disable all your modifications by placing this line at the end of your config.php. The problem should disappear.
define('DISABLE_HOOKS', true);

Do it disable Plugins & Products I have installed?

Do it disable Plugins & Products I have installed?

Yes, the above will do this, and in this case it is the best way to start debugging your issue

[Arashdn]

But i have many plugins and i can`t disable them

In that case you'll just need to live with the database errors then. :rolleyes:

Have the same problem myself and i'm having to do it.

I get this error message:

Internal Server Error, this is an error with your script, check your error log for more information.

Where do I find the error log it speaks of?

The error_logs on my server are in a directory called /logs. However, the host could have put them anywhere so if you can't find them, you should ask your host where they are.
