we discovered last night that our site had stopped letting us view pages on our site. When you click them it will usually change the title but sometimes it doesnt even do that, but always throws up a 404 error. I’ve been through disabling plugins and checking code we have changed but nothing has been added or changed that would make this happen. We can’t even view a page using pre-permalink links. Posts are working fine and all plugins are displaying, its just the page’s themselves.
We’ve also come across another problem, Widgets seem to be disabling themselves every few hours and we have to keep putting them back in the dynamic sidebar. Has anyone come across or know a way of fixing either of these problems?
