Not Saving after Update

I recently updated the plugin. I went to the Customizer to change an option, (show author box) it changed fine, and no issues hitting Save & Publish, but went to exit and it asked if I wanted to stay or leave the page, I hit stay, hit save again, then exit, same problem. If I hit leave it doesn’t reflect any changes I made, I tried restarting browser, logging out etc
