So I work with another website that uses the Xenforo content. When I get a notification that someone has tagged me into a post or that there is new content that has been posted, or even when I try to do anything with the website... it will begin to glitch or act up, and then I'll have to reload the webpage several times for the actual thing I'm trying to do will work. I had the owner look at the CPU and memory usage for the website, and it's not anything bad... I'm not sure what else to look for (I'm still learning about website management). Also I'm not sure which version of Xenforo the website is running, but it says 2010-2014 Xenforo at the bottom.What should I try to look at or fix so that posts/comments/changing profile pictures/etc will show up the first time while you're on the page and not after you reload several times?
