One sleepless night and it’s fixed ;-) For some reason the plugin wiped out the template, theme and stylesheet database tables. I recovered them from the backup I made right before the upgrade (so they might be not up-to-date). And since I was already messing up with the design, I fixed more things I did not have time for before the crash.

As always, please let me know if anything is still broken or if you have suggestions to change/improve the layout, menu, etc.

The forum is not working for some reason. “White screen of death”. I suspect the Google SEO plugin and PluginLibrary. No errors in the error logs. Investigating…
