I have imported my old blog from Blogger, but I see al the imported posts (and comments) empty.
For this reason I need to erase all the imported artilces (wich are all the posts) and try to import in another way, but I cannot find a function to erase all posts (more than 600)
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.
