HTTP 500 error admin panel

[Bateman]

Hi,

I'm trying to install a new site with a fresh version 5 license. Installation went okay without any errors.

After logging in with my admin account and clicking the admincp panel button I receive the following HTTP 500 error:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator to inform of the time the error occurred and of 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 can only go to the admin panel by browsing to: /core/admincp/index.php

I hope someone can help me with that. Thanks in advance.

You need to check your php error log for the error being recorded when you get the 500 error. If you don't know where to find your php error log, ask your host. Post the error here when you get it.

I'm having the same problem and I think I have identified the problem but need someone from vB to verify. There are no errors in the php log being listed.

Two causes are the most likely.

1) The baseurl specified in the /config.php is incorrect.

2) You've installed in a sub-directory and need to add a RewriteBase directive to your .htaccess file. Under RewriteEngine On, add:
RewriteBase /yourpath/

yourpath refers to the path where you vBulletin is installed.
