I really do understand you do not believe the fault to be on your side as you can apparently see the contents. BUT I have tried from different places with different machines and I do NOT see the contents. PLEASE help me with this issue and stop asking me to try, what I already did. Thank you!
I created a new admin user and with this new user everything works fine. Thanks for your help, such kind of problem has never crossed my path before. Sorry for being impatient, I felt utterly helpless.
