TagDiv Composer Error inserting images [v9.8]

Hi TagDiv,

GoalPoint.pt here, using Newspaper theme since 2014.
We are stuck on an issue that we need your help with. By the look of it, via the forums, it’s a problem shared by other users but we could not find specific info on how to solve it other than your availability to investigate it further.

Issue:

1. We have 2 newspaper installs running, one is a private staging/testing website setup, the other the production setup serving the https://goalpoint.pt/ website-

2. Being such an “old” user we have a lot of content using Visual Composer. Nevertheless, we are now starting to build new pages using the TagDiv composer.

3. Our testing went ok in stating environment, building a new page using TagDiv Composer.

4. Nevertheless, while replicating the same content/page in production we get an error message when trying to insert images, being them newly uploaded or existing in the BO:

“Invalid data Current state has involved an issue. You could try an UNDO operation (CTRL+Z / CTRL+SHIFT+Z)”

5. Useful information:

a) Staging and Production are running different versions of the Newspaper theme

Production: 9.8
Staging: 9.7.3

Note: we considered reverting back to 9.7.3 on production but this is not a solution (if one) since it would bring back another well known problem the 9.8 version fixed, the behavior of modal images

b) We’ve disabled the few plugins in production that don’t match the stating setup, with no positive effects on solving the issue so it doesn’t look as being related with the classical first suspect (another plugin)

c) We’ve disabled Cloudflare, cleaned caches, etc. No positive results either.

Can you please help us identify and fix this problem?
Do you have any immediate information you can share with us to achieve that?
We’ve also mailed contact@tagdiv.com, presenting this request for help.

Best regards and thanks for your help in advance,
