craichton Posted September 18, 2015 Share Posted September 18, 2015 Following Error i found on my Server Error Log. PHP5.4 changed to PHP5.5. The /e modifier is deprecated, use preg_replace_callback instead in /var/www/include/parser.php on line $text = preg_replace_callback($pattern, $replace, $text); $return = ($hook = get_hook('ps_do_bbcode_end')) ? eval($hook) : null; if ($return != null) return $return; return $text; } Problem must be here. Please can you tell me whats wrong here? Best Regards craichton Quote Link to comment https://forums.phpfreaks.com/topic/298213-e-modifier-problem/ Share on other sites More sharing options...
Ch0cu3r Posted September 18, 2015 Share Posted September 18, 2015 The regex pattern assigned to $pattern most like has the e pattern modifier applied. If so remove it.

craichton Posted September 19, 2015 Author Share Posted September 19, 2015 Well, i will try it on a XaMPP Server, who i can test it. I will give you the Result Ch0cu3r! Please be patient for awhile. Now i am sure it's a upgrade PHP Problem from Version 5.4. to 5.5.! On PHP Version 5.4 thee old Script works perfectly. Test it on 5.3 too. Runs absolute great. 5.5 get only this Error. Only this on Apache Error log, when i make, made a post. AccessLog, Syslog an MySQLLog give no Errors.

Ch0cu3r Posted September 19, 2015 Share Posted September 19, 2015 Now i am sure it's a upgrade PHP Problem from Version 5.4. to 5.5.! That is because the e pattern modifier was deprecated in PHP version 5.5, this is why you are getting that error. It is to be removed completely in PHP7 Quote Link to comment https://forums.phpfreaks.com/topic/298213-e-modifier-problem/#findComment-1521163 Share on other sites More sharing options...
