Ok that’s a start. I added those two lines to the wp-config.php file and it’s working a bit better, but not 100%. Also, when I go to any of the links in the drop down menu, I get a “Connection was reset” error.
As far as the “/index/” in the URLs, when I installed WordPress, I was asked to create a folder in which the files would go. On Network Solutions, I have the domain https://www.holyfacechurch.org pointing to that folder. If this is incorrect, please let me know!
