Since upgrading I've started randomly getting this error. I've tried disabling all plugins and using the default theme and I'm still getting the error.
A scripting/config error prevents the server from showing this page. If you are the owner you can find more help at the Freeola Support Centre or by speaking to a member of our technical support team on: 0871 210 9977. http://registration.freeola.net/errors/e.php?ec=500
I contacted my host and they said it's not their end. I did a little digging and found that they have PHP version 5.2.17 installed, and I seem to recall wordpress needing 5.2.4 or higher. Would this be the cause of my script errors? If my hosts aren't willing to upgrade PHP, is it possible to downgrade my wordpress installation?
