I can also confirm this Strange and Development haulting behavior.
Pagebuilder 5.0.6
PHP 7.4.33
Joomla 4.3.3
We Duplicated Pages, Renamed pages and Edited the Duplicate pages (All from back end)
We rebooted server (As we Develop/Host websites) and MOST of our changes were lost!
We did the same as above, Cleared CACHE, Worked within PRIVATE window of Browser, Used Different browser, Disabled Versioning of Article within Joomla, Disabled LESS.
Its an ODD behavior but has stopped us from Developing until Figured out. We need to be able to reboot a server and NOT lose changes.
Joomla 4, PHP 7.4 and Pagebuilder 5 are all new to us, which is WHY we are testing on a DEVELOPMENT server..
What else could be the cause of this??
(We continue to test on this and have just Noticed...)
CLEARING THE SORT order seems to reveal some of the PAGES that were not there/shown before...
(Defaults to Asending , Click Clear Selection)
