I try to delete posts from blogspot but I can't delete more than one post each time so it takes along time as we delete one by one I ask if there is a solution to delete more than one post at the same time.
Please help me as I want to renew ny blog content by delete old posts and replace them by new posts
Regards to all& cooperation is highly appreciated

I don't know that there is a way to delete multiple posts at the same time off blogspot. However, I do know that you can delete ones individually and there is always the option to edit your posts and put in the content that you would like to have there. Sometimes, we just have to put up with the way that a site is set up to do things. I do have a number of blogs on blogspot.
