Blog functions not working

I have been having problems off and on for almost 2 weeks now, and it’s getting to a point that it is greatly affecting my productivity. The good news is: Everything on the OUTSIDE looks fine. People can access my site without any problems. The problem lies in the Admin panel. I can access my Admin Dashboard just fine. Again, no problems. Once I’m in there, though, I can’t get much of it to work. It’s like it doesn’t connect to WordPress at all because the WordPress feeds like the WordPress Blog and WordPress News just say Loading… Jetpack will not respond, either.

I have done everything I could before finally coming here – disabling all plug-ins, calling my host to verify it’s not on their end, reverting back to the default, clearing the cache in my browser, using different browsers, using my iPad, using a different computer, etc. Once in a while it seems to be resolved, but then it reverts right back despite not having changed anything at that point. If I try to post when this is happening it will act like it’s posting then bring me back to a blank post and all my work is lost. Sometimes it will appear as if it is connected and working fine, but I always check by clicking on the “Visual” tab. If it doesn’t let me see the visual then I know it’s going to mess up if I try to post. I can also click “Preview,” and instead of showing me a preview it will give me a 404 because as far as everything is concerned I guess that post doesn’t exist at all since it’s not going to post.

My only hope at that point is to post from my iPad or iPhone WordPress App (not the actual WordPress site – but the app). Even that isn’t foolproof, though.

As I said, I have called my host and had them walk through some things with me, I’ve tried reverting back to square one, I’ve tried to have “computer savvy” people help me, and everyone is at a loss. I really need for this to be fixed so I can be more productive on my site again! Please help!! :/
