I now have a script in my template editor called allow-copy_script.
What does this script do and should I keep it?
One of your browser extension is inserting code into the WYSIWYG editor when you were editing your template (for example, ‘Grammarly', ‘Ad Blocker Ultimate', 'Adguard Adblocker', 'MetaMask' browser extensions are known to do just that).
You'd need to track down this browser extension that inserts code into the WYSIWYG editor when you were creating/editing your template and disable it.
Oh, this extension is doing it...
Weird, this does not happen with my templates on Active Campaign...
