GD Not Generating Thumbnails But Images Still Work

[BamaStangGuy]

When I set GD to handle images in vBulletin I can upload images fine but it will not create a thumbnail for the image, just link to it. When you click on the link the image works fine.

When I change image handling to imagemagick the thumbnails generate fine. So I am guessing GD is not configured correctly?

It's compiled into php. You can check out the configuration here: http://www.mustangevolution.com/php.php

Any ideas on why GD isn't cooperating?

Do you get an error (on-screen or in your httpd error_log) when you load "image.php?i=gd"? An example of what you should see is at the link below.

No that displays fine. It's just when trying to create thumbnails for forum attachments that it doesn't work.

I don't see any errors related to gd or images on error_log either.

This is somehow related to xcache not working properly. Disabling xcache solves the GD problem.

I've been following both these threads... When you disabled the IonCube loader in your php.ini and let it load on demand, does everything work when you have XCache enabled?

[BamaStangGuy]

Yes. I can't figure out why it works on demand but segfaults when loaded in php.ini.
