I am unable to edit or review templates in themler on Joomla 5.1.2 site.
When launching editor in Firefox I get error written in editing area of template: "Permission denied to get property "href" on cross-origin object.
In Chrome and edge the error reads: "Failed to read a named property 'href' from 'Location': Blocked a frame with origin "https://website.com" from accessing a cross-origin frame.
Have you seen this error or do you have any suggestions how to remedy it?
