There’s a known issue with saving after adding blocks in the Widgets screen, but it shouldn’t interfere with your existing widgets. Is this the problem you are experiencing?
If it’s a different issue, could you share some more details on where it is occurring and which widgets are being destroyed?
Hi, thank you!
When I wrote this post the day before yesterday widget area was changed to Gutenberg for unknown reason, may be it was till I installed Gutenberg and didn’t notice.
How can I deactivate Gutenberg for widget area?
If I activate Gutenberg url changes from xxx.com/wp-admin/widgets.php to xxx.com/wp-admin/themes.php?page=gutenberg-widgets
I don’t want to use Gutenberg for widget area.
You can still access the old screen by going to xxx.com/wp-admin/widgets.php directly, but I’m afraid the only way of reverting the wp-admin links to the old url is by disabling the Gutenberg plugin.
