It looks like a < script > has gone wrong somehow. Now if I was in control of the site I would just remove the < script > and < /script > but as Wordpress is in control I am not sure what to do. What would be the best thing to do ( I would not even know where to look for the offending < script > )?
This is nothing to do with my icons but could it stop them displaying - the website still works OK apart from the missing icons in as I say Firefox. If I get this error cleared we can see what happens.
I installed a theme update a couple of days ago and thought that could be the problem but I have a local copy of the site with the old theme and the same code in the view source.
Using the Edge and Chrome view source I have the same code as Firefox.
A note about the images: They were set using visual composer and appear when scrolling down the page. Still missing on Firefox with old and new theme version. So assuming a Firefox problem and nothing to do with the script warning?
I contacted the theme creator and they located the problem - the original site creator added some code to a custom JS file. I thought the code had been added through Visual composer.
Just need to find out how to fix it now.
removed the code in the custom JS file and I am left with below and no errors:
