1. The problem is with date format. For examle setting format as 21.10.2021 crashes dropdown. And date data stored in old versions and displayed with new date field in this format has not native look, seems like straight DB value. 2022-01-24T00:00:00+03:00
2. Thanks
3. New WYSISYG field removes new lines within the content. I suppose the reason is ignoring “next line” symbols of old editor strored in db. If we go next line in old wysiwyg editor on “text” tab and swap to visual tab we had next lines in text without any additional tags wrapping our content. But now when you set next lines in text tab, then turning back to visual – all next lines ignores. The same thing with the data already stored in db. It stores whith a specific symbol to make next line, but new editor ignores it and stucks lines together. New editor makes new lines only with setting </br> tag by clicking shift + enter in visual editor and ignores old format of next lines.
4. now it works with t.post_date DESC, thanks
One more problem on test copy of only one of the sites:
5. Pods editor. Pods -> Edit Pod -> Pod throws me this
