Problem with the Propositions Lesson in german

[ArnaldoCosta]

Apparently, there are five lessons in the Preposition Topic in german language, but I can't access the fifth lesson, and i can't go to further lessons... somebody else with the same problem???

I tried it on your account and had no trouble accessing that lesson. What happens when you try?

[ArnaldoCosta]

when i try, only four lessons are available, the fifth lesson is not there, there is just a number 5 there but clicking on it, nothing happens

[Luis]

Is this on the Web? If so, what browser are you using?

[ArnaldoCosta]

google chrome

Can you upload it to imgur.com and post a link?

[ArnaldoCosta]

Wow. Something is terribly wrong with how Duolingo shows up for you. Has it always looked this way? Do you have any plugins that would prevent showing css or javascript? Can you try a different browser?

[ArnaldoCosta]

always looked this way for this lesson...all the others were fine...no plugins... so I'll try a different browser...

[Luis]

One second. Could you send me a screenshot of another skill to see what you mean by fine? I'm concerned there is a deeper problem.

[ArnaldoCosta]

heeey...problem solved...i accessed the lesson with IExplorer...

muito obrigado, salvou o dia de um brasileiro... haha

[ArnaldoCosta]

ok.. just to be sure...this one is fine

Does it look totally different in your other browser? There should be a blue notebook for each lesson.

[ArnaldoCosta]

yes... in IExplorer its a blue notebook... as there used to be in chrome too, by the way, but in google chrome the notebooks disapeared a couple weeks ago, i dont know why!!! but i was doing all the lessons normally even with this change, but when i got in lesson 5 of prepositions the problem appeared...
