CollapsedThreads not working after upgrade from 7.5.2 to 7.10.0 Team Edition version

Troubleshooting
1

Hi,

Yesterday, we did the upgrade of Mattermost Team Edition version from 7.5.2 to 7.10.0 on Ubuntu 22.04 with DB running on AWS RDS Mysql 5.7.x version and after this upgrade CRT is not longer working. Threads tab or section is missing from the Mattermost UI and settings related to this are present in the config.json file.

grep -Ri “Thread” /opt/mattermost/config/config.json
“ThreadAutoFollow”: true,
“CollapsedThreads”: “always_on”,

There is nothing in the logs that can suggest why the Threads are not working/available. Do let me know if you need any more information.

Hi @ankushgrover,

Maybe some of the database migrations did not get applied - can you please verify the database schema version (you can find it in the about modal)?

The schema version is 7.10.0

OK, this is unexpected - it should be a number, not the version string.
Is this the screenshot from the web client or from a mobile or desktop app and if so, which one are you using?
Do you have access to the database? If so, can you please run the query:

SELECT MAX(version) FROM db_migrations;

and post the output here?

The previous screenshot was from the Web client. Also, the threads are working on Mobile app but not on Web or Desktop app.

SELECT MAX(version) FROM db_migrations;
