I had to make hardcode changes in the class.shortcodes.php file.
I wanted my popover window to work with click instead of hover and tried to put some html in it.
Okay, my question is how to save this little piece of code in a way it will not be overwritten with pagelines updates.
I don't have a child theme installed but work with the customization plugin. and work with version 2.4 on a client website.
What is the best solution here?
