Hello, i only moved some forum from category to another one and the site went in white directly, i cleared the cache manually but the problem didnt solved, i need ur help plz

Note: i didnt found in the cache folder these two files (.htaccess and index.html)

i have another scripts on my site and its work normally

i think the problem is in the forums or category files or tables only, so how i can repair or reset it ?

i need ur help and sorry for my poor english

i cleared the cache, repaired and optemized and reset both of these tables auth, categories, forums, forums wahtch, forums perune but didnt solved, i replaced def_auth, def_tehems with fresh files and also didnt solved.

but when i replaced def_tree with fresh one and gave it the 666 permission its solved directly, so the problem is solved now.

Admin please delete this post coz it will never help others because of my poor english

Thank you
