Hi!

We run a forum using IP.Board, and after the upgrade to 3.4.2. we have a problem when trying to transfer between servers.

Previously we did upgrades on an offline server, and once complete simple transfered database and files to the production server. However, after the 3.4.2 upgrade we get an HTTP Error 500 Internal server error when trying to transfer, with no further error messages in logs (we've checked apache, php error logs and more).

Any ideas on how to fix the problem would be highly appreciated!

assume you changed url and paths and database details (assuming they are different details) in conf_global.php file (forund in forum root folder)

Thanks, and yes, database details and conf checked.

We use different base-url in our testing environment compared to our production environment, could this be an issue?

remove any .htaccess files?

Thanks, .htaccess has also been updated.
