Update: I notified the company that their commenting system didn’t work with four security and caching systems, and they provided a fix this evening. It appears to work. I’m afraid to say it since it doesn’t seem to stick. The commenting system I use is known to be buggy, and only a tech can fix the problems. However, they all have big issues. Disqus has several issues, including costs, delays in posting, and the need to use their own server before it lands on mine. Some say you lose all your comments if you ever try to leave. Some people don’t want to sign up to write a comment, though you can use any social media account to do it easily.
Update: The voting doesn’t work again for some people. We will address it on Monday. It doesn’t always work the first time for me, but if I try again, it works in every browser.
The commenting system we have conflicts with caching and security at times. That is being corrected now. If I have to switch commenting systems, I will, but they all have flaws, and it will cost even more money than we will lose. We are trying again to fix this system. I just upvoted some commenters, and it worked for me. The tech said it works.
Let me know if you have problems.
