Could you please take a look at the core_members database table, if the msg_count_total, msg_count_new and msg_count_reset columns have values for the recently created member who get the PM.

Can you clarify what you mean with "notification" ? is it the email/notification as mentioned by @teraßyte ? Or is there literally no indicator for new PMs at all aka no Badge at top of the PM icon and no notification flash? When I visit the community once I created a PM via REST with this code: var_dump( \IPS\Http\Url::external( $url . "/core/messages" )->request()->login( $key, "" )->post( array( 'from' => 2, 'to' => [1], 'title' => 'test', 'body' => 'content test', ) )->decodeJson() );I'm seeing the badge with the new private messages and also the notification flash at the bottom of the page appears.

We have a new page for this now: https://invisioncommunity.com/theme-diff/

I have truncated your cache which resolved the issue. Will also take a look at your logs to see if I can find the reason for this.

You could use the Alert System for this.

Changed Status to Duplicate

Yes, the code is faulty. I have fixed this and we'll probably patch this on Monday.

I'll do some tests next week, but there is one in applications/downloads/setup/upg_107795/upgrade.php

What's wrong with visiting your ACP just clicking on "Upgrade Now" ?

Please check now:)

You should have already gotten an reply by email to your client area email address.

From what version are you trying to upgrade?

That said, if you’re using SendGrid, you can continue using it!

The advantage of the REST & GraphQL API (and Make, Zapier & co) is that even if our underlaying code changes, just like in the transition from IPS4 to IC5, the API doesn't need to change, so contrary to IPS4 plugins and IPS4 applications, most of your REST API consumers don't need to be changed, in fact I can tell that ALL my Zaps for my site just continued working fine after my upgrade from IPS4 to IC5 Beta 12.

That’s the spam service reporting him as spammer! You should get more information about this in your ACP’s Spam Defense Logs

Have you probably translated some language strings recently? Does it happen with a new language?

I have replied to this ticket on Jan 14, mentioning that we have fixed this in our upcoming 4.7.20 release

I have created a ticket to investigate this further on your community.

Are you meaning plugins or applications? If you’re really talking about plugins, where are you seeing them? I’m now aware of any place where they would appear in IC5! Outdated applications are still little bit WIP and we have an open bug report for this issue, because they trying to delete them results in an error.

Changed Status to Not a bug

You didn’t get any “The API Key you supplied appears to be incorrect. Please check your API Key and try again.” error?

As long as you’re on v4 you can just keep using it, for IC5 you can use a forum with permissions to only view own topics in combination with the IC5 assigned topics feature, or you could use a 3rd party application like https://www.ic-essentials.com/files/file/93-support-ticket-system/

There’s a setting for this in the ACP

Nothing from IPS4 will work with IC5!
