Hello

I just threw up a new forum, But the problem came to me !!
Submissions on all pages except the index is ...
I did not install any plugin / I upload my files again host / And I can not reinstall my forum! Due to the high post

The only thing I (bits vertical) / installation and removal of a theme !

If the spelling wrong, shame I do not speak much English

Could you help me with Iran forum

I'm just throwing a guess, but it may be due to the Arabic ASCII Language.. did you modify ANYTHING? Make a backup of your forum, and update to 1.6.7 and see what happens. Either that or wait for someone more knowledgeable than me,

Thank you very much !

Upgrade 1.6.7 error again !

Post screenshots of the Upgrade Error..
