Hey there, 

I uploaded my final experiment on Inquisit Web and everything seemed to work so far and no errors occur when participants complete the questionnaire. 
Unfortunately white pages occur, which can only be bypassed by Strg + B. But by doing so, some items are bypassed. 

Does somebody know how to solve this problem? I am using Inquisit 4 and so far I think, that I did everything right.
Sadly I don't really know to describe the problem better...

Thanks a lot for your help!
