ok, so without being able to see errors, I’m not sure I can help further, clearly there is something not working correctly on your site, and without fixing that, I do not know if it is contributing to the other issues you are having.

If you have FTP access, you can change wp-config to log and display errors, there are plenty of articles on the web that can do so, and several plugins that might work.
