You can quickly remove your contents by deleting them in bulk.
Alternatively, we can empty the whole blog for you, but that will remove all data including posts, pages, tags, categories, comments, and uploaded files.
Once deleted, the data cannot be recovered.
If you are sure you want to proceed, please reply to confirm the name of the blog you want us to empty.
I am having the same issue with deleting all the posts, pages, media,…
Deleting them in bulk is simply not working, it can’t not handle more than 20 posts at once, and afterwards I get this weird message:
Something has gone wrong with our servers. It’s probably Matt’s fault.
We’ve just been notified of the problem.
Hopefully this should be fixed ASAP, so kindly reload in a minute and things should be back to normal.”
