Using 0.9.7 - When uploading the zip file to SMF 2.0 RC3, the package manager complains it can't make 2 changes in Souces/Subs.php. Looking at the failure reasons for search and replace, 2 of the edits that you are trying to replace are already there. My guess is that replacement code was for RC2 subs.php. I told it to install anyway since I saw the 2 error changes were already there and the program is running and verified. I reconfirmed this by setting up a new test virgin SMF 2.0 RC3 install and got the same 2 install errors on Subs.php Find function parse_bbc($message, $smileys = true, $cache_id = '') Replace function parse_bbc($message, $smileys = true, $cache_id = '', $parse_tags = array()) Find foreach ($codes as $c) $bbc_codes[substr($c['tag'], 0, 1)][] = $c; Replace foreach ($codes as $code) { // If we are not doing every tag only do ones we are interested in. if (empty($parse_tags) || in_array($code['tag'], $parse_tags)) $bbc_codes[substr($code['tag'], 0, 1)][] = $code; } Again in RC3 the replace parts already exist.
