Reply To: Ajax problem and 503 errors on secondary language pages after update

Hello,

We have checked the issue with the default theme and we see the same: https://gyazo.com/f6b0c3733ecf317728768745fb850bd3

Please deactivate all the plugins not related to the theme check the issue, If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.

Best Regards
