Cannot edit and save page using TagDiv Composer

Hello,
When I try to edit and save an existing or new page, I get the following error:
Invalid data Current state has involved an issue. You could try an UNDO operation (CTRL+Z / CTRL+SHIFT+Z)

My site is using WPML. The error happens only in one language (Russian) which previousely was the main language of the site. Now I changed the main language to be English and also I added Turkish.
Looks like after that I cannot save the page using TagDiv Composer.

I don’t know if this issue belongs to WPML or TagDiv. Who shall I contact and how to investigate the issue?

See the video for details:

This is actually my topic. But it is not related to this issue. I don’t understand why do you refer to it? Because I create the page manually from scratch. It is not about translations and not about base64 issue.

FYI, I also contacted WPML support. We did the below exercise with them. But the issue persisted with minimum set of plugins. So they advised to contact TagDiv support.

I kindly ask you to follow these steps in order to isolate the cause of the issue:
– Create a full backup of the site
– Update any outdated plugins or themes
– Flush any cache memory that might exist
– Deactivate all plugins, including the WPML ones
– Activate a default WordPress theme, like Twenty Twenty
– Activate the WPML plugins
– Create a test page in Russian and check if there is any error
– If there is no error, then activate tagDiv Composer
– Create a new test page in Russian
– If the issue disappeared, start by activating the theme and then the rest of the plugins, one by one, until the issue appears again and you find the culprit

Hello,

Sorry, but due to many other issues with WPML and Newspaper, I have decided to recreate the web site from scratch. So, please close this ticket.
