Serious Mistakes after doing the last Newspaper Update

Dear ladies and gentlemen,

I am working with newspaper theme already long time now. Never there were problems and i was always happy with thos noce theme. But now it becomes serious.

I write you because I have a serious problem after doing the Update to Newspaper 10.3.5 from Newspaper 10.3.4.
If I now try to create a new page it works. When i save it and when I later open it again then error messages will appear. I cannot work anymore woth the theme then.
Creating the page works, but as soon as I open it again, an error message appears every time. This recommends restoration with the “ReDo” button. The entire content is then lost. I then save and there is a positive confirmation.
If I then open the file again to continue working, the same error message appears again.

I’ve only had this problem since I made the last update of the theme this morning (Newspaper 10.3.5).
Now I can hardly do anything more and I think it will take the whole weekend until you can help me there?

What can this be and how can I not lose my page or can I continue to work normally? I cannot create a new page, because this error come always. even if you only a row or one image inside.

I urgently ask for help.

In addition I tried now to add a text. It worked. Then I saved the article and i do a preview the text is there.
When I open again the article then the error appear again and I have to do a redo and the text has disappear.

Have I do go back to the last version og theme or install it new? May be I lose all my settings.

I tried to solve the problem and went back to the previous version of the theme. But the problem is still there. So i cannot go on with my work and need really help.
Thank you for your kind support

Its really crazy. I tried another thing. I opend not thr TagDiv Composer I opend the eidt mask. And saved it there. Then if you open the Tagdiv Composer all is there. If you go on with your work there and save it then mistake comes back if you open the backend again for work. Something is defenitly wrong. I never had this before.

I continued to try to get the problem under control and narrowed it down:
1) I can work in TagDiv Composer and create a Page and save it.
2) If I open the File in TagDiv Composer again the error message you see on the Screeshot s sent yesterday appears.
3) Then I close the file without saving again or press the ReDo Button as recommended by the Message
4) Then I open the file in “Edit mode” and save it there. After this I can open the File in tagDiv Composer again without Error-Message but only with the yellow Message that this File Was not created by TagDiv Composer. If I do so my work appears as I saved it before.

So whats wrong there or how can I get a working theme again without losing my Bolg articles and th Webpage which is already good ranked by Google after a lot of work over years?

I red the article concerning Shortcodes in the TagDiv Composer. I think thats the Problem.
I have a lot of tables to publish. So i use TablePress, which is a very common Plugin and put in the shortcode with the column text element. It never had problems.
And I need a Audio-Player. I put in this Player as well by shortcode.

I think that’s the real shortcoming of Newspaper Theme. From the beginning, in this otherwise fantastic theme, the lack of an integrated audio player and no working way to use a simple shortcode was and still is a real disadvantage compared to other themes.

I tried to create a page only with elements out of the TagDiv-List. But error message is still comeing
