Also, after installing a new theme, members are not able to see an updated forum. Some complained that their conversation and post is missing but when i check it has something to do with the browsers.The posts and conversations are there but they can't see it. After changing to another browser or reinstall the browsers, it works. That is a weird problem for me.

The only thing i can think of is the addon i installed, https://xenforo.com/community/resources/force-unselectable-style-change.4388/

If you submit a ticket with admin CP and phpMyAdmin (or similar) details, we can look into it. This error would indicate that at least one user is ignoring more users than the system normally allows. Some of the users they ignore will have to be removed.
