500 Internal Server Error

[JVCode]

Since having VBSEO installed last night, i've been getting nothing but problems, firstly with 404 errors, then with the main index not showing unless /index.php was inserted into the end of the URL (Not solved either)., and now, nothing but 500 Internal Server Error.

IF anyone has had the same problems or knows how to fix this problem, any help will be much appreciated!

Regards,
J

You have to ask for support in vbseo.com if you are sure that your problems are connected with their code:)
