OK. We made a step forward: 3 plugins are involved somehow.
You can saw at demo video – I activated all available add-ons at URE Settings.
I activated Custom Post Type UI plugin and re-tested an issue with my own test settings and data of course. There is no JavaScript or AJAX error when I open ‘Post Grid’ element for editing.
Can you repeat an issue at the site copy with a test database, which you can share? I mean I can download than the files and database data and easy reproduce a problem at my development environment in order to analyse it and offer a solution.
