I want to change the widget title from h2 to h4. I’ve seen the filter code I need to use, and read I should do this either by using a code snippet or by making a plugin. I then made a plugin, inserted the code, and nothing happens? Do I need to link my plugin to the theme somehow?
Is there somewhere special I should put the shortcode I got from the code snippet plugin?
There shouldn’t be any shortcodes.
All you should need to do is to install and activate Code Snippets, create a new snippet, copy and paste the code above then save and publish to run in the entire site.
