Collections not working-“Solved”

[Nervus_Energy]

[Edit] I fixed this by creating a new movies library and deleting the troublesome one.

Server Version#: 1.40.0.79980c29d4c0c8
Player Version#: 4.123.2
Windows 11 version 22H2

In the web player, I recently went to Movies/Collections, and all I see is

I can’t even go back to Recommended, Library, or Categories because the menu at the top is gone.

I tried the PlexDBRepair1.05.00 tool and the Plex SQLite.exe to integrity check, vacuum, reindex and finally recover. Nothing worked.

I haven’t touched my collections in over a month.

I don’t want to trash the database and re-add my libraries, I’ve done so much work fixing Matches, fixing posters, creating Collections, it’ll take me months to rebuild. I have about 4,500 movies and over 7,000 tv episodes.

I could live with just deleting the collections manually from the database if that’s what I need to do. But I can’t find any other help online. I hope someone has some advice for me.

[Edit] Today, I thought I’d look at the browser console and I see this error:

Error: “collection” is not mapped to a media type

Does it work in other apps like the mobile app?

[Nervus_Energy]

Huh, yeah, it’s fine on my Phone. That’s weird. Does this help figure it out?

[BigWheel]

In the web app in settings hit the Show Advanced button to show the DEBUG setting then in DEBUG hit the red “Restore Defaults ” button. This resets the web app ( you will need to pick libraries to pin to sidebar).

This will essentially clear the site data for the web app in the browser and hopefully reload things correctly. ( It does not affect server settings)

[Nervus_Energy]

Sadly this did not fix the issue. Thanks though

[BigWheel]

Does it work with the web app at https://app.plex.tv which is at version 4.124

[Nervus_Energy]

Did not, but it’s a moot point now. I created a new Movies library and deleted the old one. Problem wasn’t not solved, but it is gone. Cured the disease by killing the patient as it were.
