Got an e-mail from my webhost that they were discontinuing service, so I went to check a domain I have live, but haven't updated in many years. http://chapter50.org/
Site worked fine, and I went to clear out over 1,000 accumulated spam comments.
After getting tired of doing it 50 at a time, I went to the "screen options" and tried to "Show 200 at a time". When I clicked, it locked up the whole page. Going back to the wp-admin page, I got a 403 error.
Now every page in the site is 403, I can't access my admin page, and after speaking with tech support at the hosting company, he acknowledged that there have been no changes to any of my hosting records.
What should I try next? What questions am I not thinking to ask?
How do I get my site back?
