@ Michael: indeed it looks like. Starting from a ggb file, the wiki opens without any problem. But I get similar error pages when I try to open the wiki pages in which commands are linked, as https://wiki.geogebra.org/d...
I learned that after reloading the page two or three times I can acces it, but never from the first time. Maybe it's a similar problem and keeping reloading works?
The same problem 
Bij welke actie krijg je deze foutmelding, met welke versie van GG en OS van je computer? Dit is echt te weinig inormatie om iets mee te doen.

Which URL did that error come from?
(@Chris: looks like the wiki / manual)
