Hi,
just upgrade from 1.4 to 2.0 beta3 and all working fine but admin button. I get this error
Fatal error: Cannot redeclare optimizetables() in /home/forumdot/public_html/Sources/Admin.php on line 308
when trying to enter in admin pages. Topics, Post upgraded without problems.
EDIT: Thinking better my forum was in Portuguese language. Before upgrade I changed it to English. When finishing upgrade a notice to some languages files was shown and I choose continue. Then it appears some error message that quickly disappear and I receive a message that upgrade was finished. When I browse to my site it was in Portuguese again so I think this can be the problem. But I cannot enter the admin to change it to English...
