I've done a clean install of Joomla 4 and installed the Travelia template. I've updated some backend information (added my email and license) per documentation instructions. I went to edit a page using Joomshaper on the frontend and get this error:

0 array_replace(): Argument #1 ($array) must be of type array, string given

On the frontend, at https://rvfuntravels.com/ I also get the same error.

If I go to another browser or incognito, the page opens fine (though my template install images don't work) the pages loads with no errors.

Please advise, thanks, Tim
