Hi. I'm hosting my forum at technologyisfun.unaux.com. I'm not hosting it though, a company is doing it for me. I'm using version 7.0.19. how do I upgrade to the latest version of Vanilla?
The latest version of Vanilla Forums is 2.8.3 I believe 7.0 is your PHP version. Ask your hosting provider how to change that. If the version is a typo and it is Vanilla Forums you need upgraded then check this https://docs.vanillaforums.com/developer/installation/self-hosting/#upgrading
Did you install Vanilla through Softaculous control panel with your web host? If so, and if Softaculous has the latest version of Vanilla, you should be able to update Vanilla through the Softaculous control panel. Always make a backup of your files and database before doing so.
