The reason has been found the website had changed the "thumb-member-username" by "media-meta-member". So change the extractor accordingly:

Fix #31273

Pardon me, but how is this PR a fix for issue 31273?
That one pertains to ADN (AnimationDigitalNetwork), while here it's "motherless" the service in question ...

Unless I'm missing something, this PR fixes #29626 and its (recent) duplicate #31128 😉 ...

[xiyue077]

Never mean to be 31273. Must be a typo :bump
I remember I did a search before open the pr. How could I miss the #29626? :bumpagain

[dirkf]

I suspect JS autofilling ... Anyhow this extractor now has no open issues!

[Vangelis66]

Thank you both 😄 ; for correctness' sake, could either one of you remove the reference/link to (wrong) #31273 from the description of this PR (first post) ?

[xiyue077]

done.

[Vangelis66]

done.

Thanks 😄 , but you can leave #31243 out 😉 ; "Fix" inside the description is meant to reference/link open issues that will be "fixed" by said PR, while #31243 is the "id" of the PR itself, not of an open issue... Sorry for being that pedantic... 😺

[xiyue077]

done again.
No worries Vangelis66. It's just a few twitches of fingers
