  • Varnish Caching Issue

    My site is

    I would really like to upgrade to vBulletin 5 but customer service said we need to fix some problems before upgrading.

    We are currently running VB 3.8.8 with vBadvanced CMPS and TapaTalk plugins and we are seeing function issues related to thread posts, recognizing new posts, mobile posting, and also login. I tried disabling the plugins but it made no difference. Can someone please help me figure out these issues? I'm not sure where to start.

    More information is needed. Can you post the specific steps to recreate your issues? Also provide the necessary information for your server such as PHP Version, MySQL Version, Web Server and Version.

    Also, I would recommend upgrading the site to 3.8.10 as the issues may be related to the version of PHP being used.

      Thanks Wayne. Here are the specs:

      PHP Version: 5.6.29
      MySQL Version: 5.6.32-78.1
      Web Server and Version: Linux 3.12.65-20161020.132.ELK6.x86_64 #1 SMP Thu Oct 20 23:36:20 CDT 2016 x86_64

      If I view threads with new posts, leave the site and come back it sometimes shows the posts as being unread. Other times it shows new posts as being read.
      Sometimes If it will look like a thread has a new post. If I go in and take a look, I don't see anything new until I refresh the page.
      If I try to log in, the site looks like I haven't logged in until I navigate to a thread.

      I'm not sure how easy it is to upgrade to 3.8.10. I'd rather purchase the vBulletin upgrade and have you do it and trouble shoot these issues. Is that an option?

        Please lower the cache revalidation time.

        Kind regards,

          I think I fixed it. I found this thread:

          and contacted Bluehost. We upgraded to their Cloud hosting at the beginning of Feb. Apparently Varnish is running. I was able to disable it and now everything seems fine.

            That would do it, Varnish is very bad for forums.
