Hej,
the errors you got were because for a short amount of time we had a misconfiguration in the database, parts of the template were linking to the development server and not to the official one.
On the other hand, I am taking your suggestion regarding php.ini, thanks.
Also, the navigation paradigm when it comes to the logotype is something we have standardized for this new forum. The Arduino logo, at all pages, should link to the main site, while the tagline should bring you to the homepage of the service you are logged in at the time (forum, blog, playground, etc).
