wiki captcha error: preg_match Unknown modifier 'p' in EditPage.php

[lbecchi]

often, mostly when external url are present in the content, the editing of the wiki page requires the captcha even if already confirmed.

on top of the page is visible a PHP warning:

<b>Warning</b>: preg_match() [<a href='function.preg-match'>function.preg-match</a>]: Unknown modifier 'p' in <b>/var/www/mediawiki-1.11.0/includes/EditPage.php</b> on line <b>645</b><br />

when editing massively it starts to be a problem to add captcha to every

commit.

I don't have access to that php page so I can't analyze the bug.

Whoever has power to upgrade the wiki to a new version has power to see that file. Also that file is just a standard MediaWiki? file that does not get customized by any program.

Anyway, there are lots of Google results for the keywords in the error message... must be a common problem.

Anyway, in my wikis, I don't load up on the extensions, (but as my wikis are Chinese, I just filter on "no Chinese? must be spam"...)

Also reported in Bug #318.
