Thread:Project:Support desk/Cannot seem to secure my wiki from unauthorized account creations, edits, etc.

MediaWiki 	1.15.2 PHP 	5.3.5 (apache2handler) MySQL 	5.1.54-log

I have a Mediawiki installation at Climatewiki.org. Over the past several months, we've had many occasions of unwanted spam entries, even edits to existing pages. After each episode, I would discover the LocalSettings.php had been modified back to less-secure settings. I'd replace it with my more-secure version and things would be fine again for awhile.
