I also try to “add” jqueryui 1.10.3 in the admin section using Custom Css and JS
<script src=”https://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js”></script>
I can see the content bloc when I open the page/article edition but then nothing works anymore:
text/content can only be viewed in text mode (when Visual is activated, editor does not appear and content is lost)
media cannot be used/selected
So to use this “hack” is absolutely not a solution and Powerbuilder programmers must provide a version compatible with WP 5.6.
Re-implement the ui-elements is a real big job. Ok if it can be automated but not ok if every single bloc should be changed manually.
Hope we can find a valuable solution with this issue.
Regards.
