So you have to turn on php-error-messaging. Or install same version on an local webserver, where you can savely turn on error-messages and retrieve the errors.

Another suggestion: return to original files and carefully follow every step you made...
Thank you for responding Miriam_T..

After searching this thread for "White Pages" or "Blank Pages", then reading a multitude of related users having similar problems.. DrByte had included a link for the PHP_Debugger Tool for another user, one of his contribs, I'm sure. I ran it on the failing side, as instructed, it told me that I had made a similar declaration in another file, I looked at the other file, "ezthumbnails", I tucked it into an isolating folder, reran the failing Catalog, viola !! There seems to be some alignment problems in the right sideboxes now, but way better than a dead site. All hovers and enlargement features are working. Thanx to the both of you.. I highly recommend that all NewB's grab this file.. it looks like a life saver.
