The behavior of memory_limit has changed a bit in PHP 5.2, but if it
still runs ok with a 20M limit then the problem is most likely that your
provider's memory_limit configuration has changed since you installed
MediaWiki.

The installer would have set the 20M limit if it detected a smaller
limit at the time; if it didn't, then either there was no memory_limit
or the setting was at or above 20M.
