Can't test my site anymore.

I’m trying to run a test on my site (http://ablemagazine.co.uk) but I keep getting a (Error: 500). My webpage loads fine and the test works fine for other sites on my server :huh::huh:

I seem to be able to test it just fine… which location were you using? http://www.webpagetest.org/result/110224_DV_9b406d0ac8bc2ae1218f6c0fa41b06cf/

Looking at the 7+ second server response times I wouldn’t be surprised if the 500’s were driven by the server being overloaded.
