Thanks for the response Chris.
I’m not sure you are correct. All css and js files are loaded within the theme using get_template_directory_uri() but only the less file is throwing an error. I think it has something to do with how less is generated.
The theme is using get_template_directory_uri(). To load the stylesheets which should return the current sites domain as the base but they are loading from the mainarray.com domain.
As stated this is multisite install. My other sites and themes on this install load styles, images etc. from mainarray.com (the domain which WordPress MU is installed on) without error.
Also to note the wp-content directory has been changed to uzsources. Are you following the Codex guidelines for moving wp-content?
The content directory was renamed using the Better WP Security plugin which has never been a problem before and again, if it were the cause, I would be seeing the error on other sites on the network. However, before I came here I did disable all my plugins just in case.
You can fix this by adding the following line to your virtual host file
Header add Access-Control-Allow-Origin “https://mainarray.com”
Header add Access-Control-Allow-Origin “https://tracesofviolet.com”
Shouldn’t this be avoided for security?
Thanks
