I have installed and enabled BBcode, BUEditor, Extensible BBcode and Advanced Forum modules on my site. I would like use BBcodes to post the topics in forum. When I post the topic with any value [for e.g [b]this is a test data[/b]] and submit the posting I see the raw data displayed without BBcode formatting.
Not sure what is going wrong. I see the errors in the drupal logs.
Warning: preg_match_all(): Compilation failed: unrecognized character after (?< at offset 5 in XBBCodeFilter->process() (line 42 of /var/web/sites/all/modules/xbbcode/xbbcode.filter.inc).
Appreciate your help.
