Please deactivate all the plugins except these ones:

Switch to the parent theme and check if it appears.
If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.
Please, confirm the permission for plugin deactivation, and switching to the parent theme. As soon as we complete the testing we will enable all back, however, the site would be without plugins for 15-20 min. You would better make the full backup of your site.
