Hello,
I faced the problem of same “Ajax error” as this.
This error takes place, when it changes to URL which starts in “https://.”
They are pages, such as “Cart” and “Contact us.”
And, I tried the solution read on this page.
When giving this method, the message of “Ajax error” stopped appearing.
But it has not resulted in fundamental solution.
The address bar of a browser “Chrome” has still shown the warning of an error.
In addition, when not using “Where did they go from here”, an error does not take place.
Is there any method of solution?
Thanks in advance.
