@ryoken, check the titles again to see if thumbnails work for you. Do this by going to a view that will give you a thumbnail such as quick search of the title.
For example: https://mangadex.org/quick_search/quark

The thumbnails show for me. (Edit: to clarify, I tried each of the series listed above and was able to see their thumbnails.)
Note: The thumbnails have been moved now, so your thumbnail links won't work.

Known, the thumbnailer has been broken for ages.

@Noms, thanks for letting me know...

@ryoken I hope you can see them! Try a hard refresh if you don't.

As Teasday said, thumbnail problems are common. Sometimes it can be a problem with the image file that was uploaded, so it's still good to have another set of eyes check them out.

Solved now, at least for my PC ?
