If you have tried the plugins, I’m not sure what to do, but I was having a problem with not being able to edit as well. If I clicked “edit” or “add new” it took me to a blank screen. My Picapp plugin was the culprit. That same plugin has also caused other sites I have to hang up and take a really long time to load. I have quit using it now because it just wasn’t worth the trouble. If anyone reading this has it installed, you may want to try turning it off.
