Many moons ago I commented on the lack of suitable updates to the installation of PHP on 1and1 shared hosting. At that time, I changed a setting called global php version from the standard php 5 to the unusual php dev in hopes of finding a special hiding place for PHP 5.3 support. Today, it kicked in for the first time. Badly.
This blog and The-Nexus.tv went down to memory allocation errors caused by PHP 5.4.3. To fix the problem, I simply reverted the change I made months ago (though at the time had no actual affect) from “php dev” to “php 5″. Everything went back, seemingly, to normal a few minutes later and I began writing this post. You might want to watch out if you’re using 1and1.
