Forum Rebuilding Attachment Thumbnails - Doesn't work?

[محروم.كوم]

Hey guys, I was trying to rebuild my attachment thumbnails because I changed the settings in the admin cp, but when I try to do it, it shows me this:


Code:
Building Attachment Thumbnails
If you receive a fatal error or if the process seems to hang, you will need to delete the last attachment listed on the screen then refresh this window.
Processing: Attachment : 37 (jpg)
And never moves from that spot. I've left it there for an hour and it still didn't have any change.

Any ideas on what could be wrong? Thanks! __DEFINE_LIKE_SHARE__
