I have had this problem for the last 24 hours. I originally thought it was an issue with a plugin, but after deleting all plugins, it ended up being something to do with WordPress.
I tried all the options offered on the forums with no luck. I tried completely deleting the wordpress site then deploying it fresh as V4.5.2. Same problem.
The only thing I could do to fix this was to download V4.4 and restore the folders and files over the top of V4.5.2. Once I did this, it was back to working fine. Now my plugins that werent working are now Ok too.
