Hello,

Please deactivate and delete these plugins CMB2 and Redux – they are no more needed.

Then deactivate all the plugins not related to the theme and check the issue again. If the problem has gone, activate the plugins one by one to detect which one causes the problem, if the problem remains, leave the plugins to deactivate for us to check.

If you cannot keep the site without the plugins confirm the permit for us to deactivate for the while of checking what may take up to 15 minutes.

Best Regards
