Hello,

I just upgraded from 1.2.2 to 1.2.4 and flicked through the albums to check.
All looked fine and then after a while this errors occured:

Notice: session_start() [function.session-start]: ps_files_cleanup_dir: opendir(/shared/sessions) failed: Permission denied (13) in //gallery/zp-core/admin-functions.php on line 9

Warning: Cannot modify header information - headers already sent by (output started at //gallery/zp-core/admin-functions.php:9) in //gallery/index.php on line 112

Warning: Cannot modify header information - headers already sent by (output started at //gallery/zp-core/admin-functions.php:9) in //gallery/index.php on line 113

I reloaded this page (default theme, a page 4 with thumbnails somewhere in the midst of my images) and the error was gone.

What happened?

Thanks, Michael.

No idea. The backend runs with sessions enabled. Somehow that one time PHP had problems accessing the folder where it stores Session Information.

This is not directly something Zenphoto has control over.

ok, since that occurs one in a while and I don't want to bother visitors with error messages I collect them into a log file.
If it doesn't get better I'll talk to the provider.
Thanks a lot!
