Update: So I may have been a bit hasty. WooCommerce kindly did a test, and like @shanebp was also unable to replicate the results of the issue with friend requests not accepting.
Despite infinite load I was experiencing, I could right click the “accept” or “refuse” button with a friend request, & copy the URL that indicated the nonce and open it in a new tab and then it would accept/refuse the friend request.
After scouring for hours and hours through different *old* threads regarding similar issues I did discover a few individuals that seemed to have the same issue, but there was no resolution presented. I figured that there were several people, then (at that time) having the issue, and if it’s just me having the issue now – perhaps, it was something wrong with my copy of BuddyPress…
So, I finally decided to delete my installation of Buddypress directly through sFTP and reinstall a clean copy of it from https://wordpress.org/plugins/buddypress/ directly back to the sFTP. I guess that was the solution.
I am still unsure what the issue was, or why it was (at least on my installation) causing this error.
However, I am now pleased to report that the issue is resolved and that I am able to accept friend requests.
Thus it merely appeared that it was WooCommerce because this was the plugin that seemed to trigger the infinite load when I was doing disable plugin testing to see where conflict appeared.
