Hello and thanks for your reply!
I did try both in Chrome and Firefox but was having the same issue with each browser. There were no error codes that I found.
Oddly enough, when I tried your suggestion of using a different PC, Wordfence is working again. So, the good news is my website seems to be working fine but now I have to investigate why my PC is acting up!
Thanks so much for your attention. I will mark this issue as resolved and hope that it will stay that way.
