i had 1.5 installed, everything was working fine. i decided to install a template called PURE AQUA. soon after, i logged into the admin and selected the template & hit update (tools > template selection) ... after doing that all i got was a blank page whenever i tried to view webpage. safari & opera displayed a blank page ... i tried copying the backup that i had made prior to installing the template ... still no luck ... i then removed the zen cart installation & reinstalled it ... i was able to see a website .... i tried copying back the files that i had backup ... but no change ... i am unable to get my old website back ... i am new to zen cart ... any assistance would be greatly appreciated
