Okay, so I goofed.
I've had the same blog title but then one day decided to change it to something else. I then realized that was a bad idea.
I then decided to change the name back but it wouldn't let because because it said my old name was still in use (I own both names).
I've tried the import export feature but that only transferred the texts of my posts and nothing else; it's actually made things worse.
I want to just change the name back to how it was before, how do I do that?
The blog I need help with is reformeddude.wordpress.com.
