Hi MagnificentWorm7 , what version of ClearML server are you running?

Could well be the same as https://github.com/allegroai/clearml-server/issues/112 which is also discussed https://clearml.slack.com/archives/CTK20V944/p1648547056095859 🙂

Does it give you any error while deleting the experiments?

also, all dataset don't have any dependency(parent) on other dataset

It says some files not deleted on several experiments. But the files also not deleted on project which error not occurred.

Can you hit F12 on the browser and see what happens in the network area when you're trying to delete?
