Update to 1.21.1 results is error string(2) “no” for admin panel

I am having the same problem with version 1.21.0.
I used wp-cli to solve it for now:

$ wp plugin list
+---------------------------------------+----------+-----------+------------+
| name                                  | status   | update    | version    |
+---------------------------------------+----------+-----------+------------+
[...]
| publishpress                          | active   | none      | 1.21.0     |
[...]
+---------------------------------------+----------+-----------+------------+
$

Switch off:

$ wp plugin deactivate publishpress
Success: Plugin 'publishpress' deactivated.

Admin menu is once again available…

I confirm the error! I had to disable the plugin. Does the developer not test?!!!

Hi @antomal @evelien @tpnotes

Our apologies for this. The PublishPress update is rolling out successfully to almost all sites, but there must be something about your setups that we missed in testing.

It could be a particular hosting company, PHP version, or plugin conflict that we didn’t test for.

Please email help@publishpress.com with some details of your setup and we’ll get this resolved.

Our whole team is working to correct this error as quickly as possible. We have identified the cause of the error and will release an update very soon.

@tpnotes @evelien @antomal PublishPress 1.21.1 is released to correct this error.

That was really fast – thanks a lot!

It works! Thanks guys!

I have re-enabled the plugin in my site.

Now the only confusing thing left in this discussion is that the fix is in the version that was named as the culprit in the title of this thread…

It was my mistake, when starting that thread. Unfortunately, I can not change the title.

This bug was in v1.21.0 and is fixed with v1.21.1

No problem @tpnotes – thanks for posting the clarification.

Sorry about the original bug, everyone. Here’s a quick explanation of why our testing didn’t catch it … it only showed if you’d been using PublishPress for some time and had performed a particular action.

After a month, a message pops up asking for a review of PublishPress here on www.remarpro.com. That message has 3 choices: “Yes”, “No”, or “Remind Me Later”.

If you had clicked one particular choice, you saw this bug. For everyone else, version 1.20.0 worked OK.
