I just deactivated all my plugins (12) and it started working. I think I’ll activate one at a time and see which caused the problem.
hI,
1. Generally, it is due to the plugins which creates this kind of problem….so you can either deactivate all plugins from database…And reactivate one-by-one to find culprit…or rename the Plugins directory via FTP.
2. From wordpress admin area -> Appearance-> Widgets under Screen options, try the Enable Accessibility Mode.
3. Delete or refresh the browser cache.
Thanks,
