Blank Page after Update

[Anrulz]

Hi there, I had issues and problems with my cpg ... it was from 2009 from a backup, to refresh my gallery I uploaded latest cpg, I ran the update.php, gave the admin login info, said everything is successful and updated ... so I wanted to go versioncheck site and all was empty, blank!Then I wanted to go to the main page, index.php but same all white, blank!Any hints?I unfortunately cant give my gallery url right now because I am using a backup from 2009 and the website is very vulnerable, but I can PM the link to support members if necesary.

Best regards,
Anrulz

I added some extra codes to index.php to show debug, error but nothing showed up, I edited config table from phpmyadmin still no errors, I deleted all languages except english.php still blank page, the theme was classic, still classic, I  changed it to curve and then again classic but still nothing changed ...all is the same help me out guys
