Broken website

review: https://codex.www.ads-software.com/Changing_The_Site_URL

OK, I went back to my host and changed the site URL back to the original directory as explained in the above post. My issue is now that when I test getting email subscriptions to my blog for myself, my email shows up wanting me to confirm my subscription to https://buellreview.com/testing123/ instead of https://buellreview.com/.

Meaning email subscriptions are somehow still in the deleted unused directory. How do I change the /testing123/ directory back to my default since that directory was deleted at my host through PhpMyAdmin?

Everything else but “Subscribe to my blog” seems to be working as it should. this would explain why I’m also having trouble with Feedburner subscriptions. Is the directory error something I need to deal with at my host or wordpress?
