Ok, so Godaddy have resolved the issue. No idea what the problem was, so can’t help out in that department. I can only assume it was a hosting issue when they upgraded to the latest version of wordpress.
Yes, also spoke to them at length yesterday. They have said they will look further in to the problem (they were stumped yesterday when I spoke to them) and let me know. Ill let you know the outcome , if any, when they get back to me.
May I ask which theme or theme developer you are using? just to rule out a theme compatibility problem, if there is 1. I am using chimp studio.
