Hi,
Long time use of Zenphoto, tried upgrading from 1.4.4.4 to 1.4.5.1 today, setup ran OK but when the green ticks appeared for plugins I noticed one of them was just a black rectangle, setup then took me to admin page but when I viewed the site, I got a error message saying that class video was missing from line 49 of class-image.php I am now in the process of going back to 1.4.4.4
I have 4 installs of Zenphoto to do so will try the others until I know what the issue is, I do have customised themes.
Thanks
Steve
