Hi – I just completed an upgrade from 5.1.4 – 5.2.2 on a WordPress 3.5 Multisite. I have attached a screen shot of how the forum appears and the full environment screen shot. The following information is provided for troubleshooting:
1. I did the update manually as the auto-update did not work (takes me to network home plugins update each time with no upgrade option – upgrade option only appears in plugins directory for the specific site using it). I removed the old 5.1.4 plugin and replaced with 5.2.2.
2. I went to the particular site using simple press – and ran the upgrade from the menu (successful).
3. I went to the site and get the view shown (screen shot) – there is a small spinning wheel shown. All of the data appears correctly – but does not get rendered in the theme.
4. There are no errors shown in simple press admin console or Apache web logs –
5. I downloaded the latest default them and replaced the existing – same issue.
6. I restarted Apache – same issue.
7. The site leverages Elegant Themes Aggregate Theme with a few minor font changes only.
