Hi, please help,
HTML editor showing weird code as per screen shoot. Is there any PHP modules that need to be installed?
I suggest re-uploading Sendy to make sure all necessary files are uploaded:
Download a copy of Sendy from https://sendy.co/get-updated with your license key (use the form at the top left of the page to download Sendy).
Then re-upload all of Sendy's files to your server (except /includes/config.php and /uploads/ folder) replacing the old ones.
Make sure all necessary files are uploaded.
If that doesn't resolve the issue, it is very likely that one of your browser extension is adding code into the editor when you were composing your email.
If the issue is resolved, then you’d need to track down this browser extension that inserts code into the WYSIWYG editor when you were creating/editing your campaign and disable it.
