I’ve spent two days writing code to isolate and get around the problem, to no avail. I do have a suggestion for the author(s): Rename your tagDiv files so that they are not the same name as those called by the other theme. Perhaps by adding the name of your theme to the tagDiv file names throughout the theme. Unique file names (everywhere!) would eliminate the compatibility problems. I gave up and moved my new site out of the multi-site WordPress and onto a new install.

A step-by-step explanation would be helpful. Saying something should “look like in my screenshot” without first explaining what should look like your screenshot is not helpful.
First, I click on the Column title and see the title text is <span id=”td-animated-element”></span> marketing<br>generates results

What do I click next to change the span id? If it is the raw html, where do I place it?

So much of this has become needlessly complex. I would have thought the purpose of providing templates was to simplify the process of creating pages/posts/content.

Same problem. I’ve emailed you.
