Text with title element

When I create/edit a page and go into TagDiv Composer, I can add a row. But when I try to add a Text with title element and try to Edit Content, the WP Editor just hangs with the loading icon. It never renders.

Here is a link to view along w/ the Console log: http://take.ms/xejlZ

Thanks for you guidance – it was a rookie move on my part. It was a plugin that was causing that initial WP Editor issue. However, I have new problems.

I have disabled all plugins except for the tagDiv theme plugins. I completely removed the Newspaper theme and re-installed the Newspaper 8.5.1 update theme. The issues I am experiencing are below:

1. The left column editor in the tagDiv Composer appears to have a styling/display issue: http://take.ms/RF2ba
Actually, when I first installed Newspaper 8.0 – the left column had some spacing issues. It appeared to be cut-off a bit. But now it is worse in 8.5. The Layout dropdowns are missing and when I try to change I get invalid row change detected errors (as seen in the link example above).

2. When I updated to 8.5, I activated the tagDiv Multi-Purpose plugin. In the tutorial I see all kinds of new elements. I don’t see these in my Composer.

I need a lot of help!
