Thanks, all, for the quick responses!
Girlieworks, your suggestion worked like a charm!
Now, when I did that dumb move, it was in an attempt to fix a previous problem that I’m still having.
I was trying to implement a redirect because my blog used to be on blogger. I want people who click a link to a blogger page to end up on the same post in my wp installation. I used the method in the article here, Step 4. https://www.wpbeginner.com/wp-tutorials/how-to-switch-from-blogger-to-wordpress-without-losing-google-rankings/
I successfully installed the suggested code in the blogger site. However, when I tried to edit the functions.php file in my theme per the instructions, there is now a redirect error when trying to open my blog at https://www.atravelfortaste.com/wpblog. The theme I was using is Virtue. When I backed out of my changes to functions.php, there was still an error. I switched to default themes in turn (Twenty Sixteen, Fifteen, Fourteen), but the error did not resolve itself. I cleared cache and cookies on several browsers on two different devices, but I’m still getting the redirect error. Also, the live preview in admin for all themes is a blank, white screen. I’ve removed Virtue and its plugin completely, still no change.
Should I open a different request on the forums for this?
Thank you all again so much!
