If you are getting double lines in your product descriptions after you save and view them then the steps below will help you fix this.
- You will need to navigate to [root]/admin/includes/classes. Inside this folder you will need to find the file class.editor.php and open it for editing.
- Once opened for editing you will need to scroll down to line 124 where it states $Content = preg_replace("#<br( /?)>#", "\r\n", $Content);
- Change this line to match this $Content = preg_replace("#<br( /?)>#", "", $Content);
- Save these changes and the problem should be fixed.
