Internal Server Error(500) when attempting to add new forums

[space?]

Hi friends,

I set up a board for testing on a new server... everything works fine but I can't use the functions

Forum Manager
Add New Forum
Forum Permissions in my AdminCP, when I try to, the system fails and immediately returns an error 500.

But all other functions work fine.

Any ideas how to solve?

Kind regards,
Alexy

500 error - typically a htaccess configuration issue.

check your web server program logs

My .htaccess:
RewriteBase /
that's it... without the line nothing will work... the board is running on a subdomain, the main domain has a htaccess as well.

And the webserver error log?

No logging for this and can't turn it on.

No error logging? Are you very sure. If so, you really should ask your host to turn it on.

whats in the main .htaccess file?

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/index.php
RewriteCond %{REQUEST_URI} (/|\.php|\.html|\.htm|\.feed|\.pdf|\.raw|/[^.]*)$ [NC]
RewriteRule (.*) index.php
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]

Removing the main .htaccess file results in no improvement.

Attempt to disable mod_security by placing it in the .htaccess file or a php.ini file if the host will allow it.

Make sure file permissions/ownership of the files are correct

Disable plugins/modificaitons
