I guess it's my fault for not updating PHP Markdown fast enough. Sorry. :-) I've been made aware of it in September, but I haven't checked it yet. It might be that a PHP update is causing it, although it seems I would be getting more emails if that was the case. Perhaps not that many people have warnings enabled, or perhaps they just silently fill up everyone's server logs and nobody look at those logs and so nobody tells me. The warning message could be clearer, but I suspect PCRE is treating specially character classes in regular expressions that starts with a dot, warning that POSIX character classes (which starts with a dot) are not implemented. The solution should be to replace any instance of "[." in any regular expressions with "[\.". -- Michel Fortin michel.for...@michelf.com http://michelf.com/ _______________________________________________ Markdown-Discuss mailing list Markdown-Discuss@six.pairlist.net http://six.pairlist.net/mailman/listinfo/markdown-discuss
