Updating thumbs after installing modpak

[lucyw1986]

I assume this is where this question would go as I've just installed modpak and it's related to one of its features.

I'm wanting to update the thumbnails in my gallery but while doing that under 'Admin Tools', on several occasions I've received this error message:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, support@supportwebsite.com and inform them of the time the error occurred, and 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've gone into my server error log and found the following information:

[Thu Jan  3 08:35:49 2008] [error] [client 82.13.92.220] Premature end of script headers: /var/chroot/home/content/s/o/p/sophiaborg/html/gallery/util.php

Can anyone help me in finding out how to fix this problem?

can be everything from server setup (php) over timeouts to memory limits

most probably imho its php memory_limit or max_execution_time

see the upload trouble shooting guide for more info
