Blank Screen when i install new themes

bunky1966

Hi all , ive installed zenphoto fine, and its running with the themes that come with the install no problems,

i have downloaded a couple of themes from here, and installed and activiated no problem but when i go to browse to the site its a blank page , i can revert back to one of the orginal themes and its all ok.

I am running the website on my QNAP Nas box.

any ideas ?

kind regards
Mark

EDIT i just realized i am running a very old version, ill try downloading the latest one and see what happens
