I wasn't aware that I was bumping - I don't post much in these forums, and I was trying hard to follow the rules. In any event I didn't, apparently, bump for 24 hours after my first inquiry with no responses. Anyhow, sorry that I caused a problem, and thank you for chiming in.
I just deleted 4 inactive plugins and then disabled all (13) plugins other than Wordfence. I ran a scan with debugging turned on.
It still seems to hang on scanning for infections and vulnerabilities and Googles Safe Browsing List. The last log entry was, at the time I'm typing this, about 25 minutes ago (everything in the log for the current scan happened within 3 minutes).
I'm not 100% sure what all are error messages, but here are some things that don't sound good. (I've included a few log file lines before and after the error. Let me know if there is a better way to format them here (code? b-quote?)

As for .htaccess file(s) - I am currently trying to delete 6GB of other non-Wordpress stuff from my server, which is taking forever, and when it's done I'll search for all .htaccess files.
