recent upgrade again has killed my scribunto. I updated to extension version 1.23 to match my mediawiki. just after I got it running I noticed this error poping up in my pages that worked previously. Since I don't know anything about Lua. maybe someone can decipher this error message.PCRE is 8.1 from PHP Version 5.5.6-1
