I am tried upgrading copperimine, but had problems with images not being found for the rainy_day theme post upgrade. I believe I tracked that down to the theme directory having permissions of 555. I notice now that numerous directories in my coppermine directory have permissions of 555. Will coppermine upgrade correctly with such permissions, or do they all need to be 755? Post update/installation, should any of the coppermine directories have permissions of 555?
Hopefully this section of the docs will help you http://documentation.coppermine-gallery.net/en/install_permissions.htm#permissions
Yes, that helps. Thank you for pointing me in the right direction.
