php-upload => blank page

[-wastl-]

hi guys, i've some problems to articulate in english, but i'll do my very best

ok, i've installed Coppermine Photo Gallery 1.4.13 modpack v2 (stable) on our vserver, no problems.

when i want to upload a picture (php upload), it leeds me to a blank, white screen. but not always?! i'm not sure, why sometimes there is a blank page, and sometimes it works?! file-upload by url works fine.

i already checked the file-permissions (/albums and subfolders at 777). debug-mode is activated, also uploading just single file allowed. but there is no error-message, just the white screen.

php.ini is standard, php-upload allowed.

at the moment, there is no test-user, i'll register one for you soon. gallery is bridged with a phpbb2 2.0.21 plus 1.53 forum.

uploads work liek a charm if you keep image files small (you may wish to delete album and pic now)

If you upload huge images then you may run into server sided restrictions.
Read the sticky thread (upload trouble shooting) for more information.

I've tried with a 2000x1333 image and got the expected result, a blank page.
Either further restric uploads (in size x/y) or increase php memory_limit

Sorry that your thread has been moved here. You strated it in the right forum (upload troubleshooting). I'm moving it back where it belongs.

additionally I suggest using the wataremark downsize functionality. That way the watermarks won't look over- or undersized for intermediate and fullsized images.

thank's for helping that fast

ok, in my opinion the problem is php memory limit (8Mb). you seem to think the same =)
i'll check, how to configure this setting and test again. i hope, i don't have to ask here again

thank's and bye
