I have also seen a fewl other problems in the main wiki page:
In Firefox, in the tab, there is a moving icon during several seconds. When this icon stops, the "Anonymous" button is active. But the login windows opens the logon for the forum, not the wiki one apparently. In Edge or Chrome, when the icon stops moving in the tab, the "Anonymous" button stay inactive;
A few links have not been correctly imported apparently.
In "Download Code::Blocks" you have : /index.php?board=20.0 Nightly builds, which is too short;
In "Other resources" Community Forums, should be a link;
In the "Supported compilers" the link to MinGW Gcc opens a
www.mingw.org, which has nothing to do with MinGW, at least on my PC (and for me, it's a site in french... strange
So, there is still work on these wiki pages after migration, but we can't help if we can't connect.
