Hi mate, you need to copy and paste this part into your database sql, if you use phpmyadmin to access your DB, go to your DB, click on SQL along the top, and paste all the below to alter/add new tables.
Code:
ALTER TABLE `torrent_torrents` ADD `post_img` TEXT CHARACTER SET utf8 COLLATE utf8_bin NULL AFTER `descr` , ADD `screan1` TEXT CHARACTER SET utf8 COLLATE utf8_bin NULL AFTER `post_img` , ADD `screan2` TEXT CHARACTER SET utf8 COLLATE utf8_bin NULL AFTER `screan1` , ADD `screan3` TEXT CHARACTER SET utf8 COLLATE utf8_bin NULL AFTER `screan2` , ADD `screan4` TEXT CHARACTER SET utf8 COLLATE utf8_bin NULL AFTER `screan3` ;
