I have a bunch of sites on a server with php5.2.16 running fine. They upgraded to PHP 5.3.2 and everything broke. Every wordpress site was generating huge error logs with this in them:
PHP Warning: PHP Startup: Unable to load dynamic
open shared object file: No such file or directory in Unknown on line 0
I really want to upgrade the server, but I have a lot of WP sites on it and it's only showing in those sites.
