I performed the latest upgrade on the plug-ins yesterday. For the most part it was successful. It did override our customizations but that’s fine. The problem now is that forum is set to display in blue which it does when accessign it via a laptop or desktop. However, when accessing it via a mobile device such as a tablet or smartphone the background is black and gold. This didn’t start happening until after the upgrade. Please advise.
If you make customisations to themes then you really do need to make your own which really only takes a couple of minutes to do. (http://codex.simple-press.com/codex/themes/theme-basics/creating-a-theme/)
Sounds like your mobile theme setting is set to the wrong overlay although I am pretty sure there is nothing in the update which would affect that. Anyway – go take a look. Forum Admin > Themes > Mobile Theme. Check the overlay being used.
