here is my website [login to view URL] i need to put categories in the forum and also need to UPLOAD BIG FILE TOO...Please ask hosters where to set upload_max_filesize 30M and post_max_size 30M. If in .htaccess then you will need to add to this file (it is in the root) lines:
php_value upload_max_filesize 30M
php_value post_max_size 30M
