Comment Section not working

Honestly I need help with all pages because my comments section is being really strange. At first, I thought a drop off in comments was because I hadn’t marketed properly my blog. But then I found out people were telling me they weren’t able to comment.

It gave my readers a 405 error or blank screen when they tried to comment. So I tried to see if I had a problem on my end. But I don’t. I logged out of WordPress and it still allowed me to post. I changed computers, got on my cell phone and all allowed me to post. So I couldn’t replicate the problem. I had blogging friends try it from different locations. They couldn’t get it to work. I tweaked a few things and then it worked for them. And now it always seems to work for them. But for these others it didn’t work. Then I tried going back to a previous version of things and that caused a massive failure. I had to reload everything.

Once getting everything reloaded I decided to try changing themes. I researched different themes and went back to one I had previously been using. I also added a social comment software to try to bypass the generic one through wordpress. Not all people seem to get it, or it loads really slowly. They get just the generic wordpress one. They say they post still and still get a 405 error. So I checked the plugins and found out a couple were in conflict and got rid of the conflicts, but that didn’t seem to work. And what’s worse, I still seem to be able to do everything just fine. So I cannot replicate on my end what’s happening so I cannot see to fix. Do you have any ideas where to begin?

I’ve already changed themes, checked plugins, and done a myriad of other things to fix this. Please help!!
