I have resolved this – I downloaded the plugin files again and manually uploaded them via ftp, seemed to resolve it right away.
The domain name it is sitting on has just recently be redirected and the DNS servers reset so that may be causing the problem.
Thanks for your help, I will look into it further and post back if I get a fix.
The live site is also showing:
09:47:08 – November 1, 2013
1 Operation timed out after 10000 milliseconds with 0 bytes received
Yes it is!
I am also seeing an error of:
11:23:31 – November 1, 2013 1 name lookup timed out
I am testing it locally, but it is also throwing up these errors on the live site – any ideas?
