We have this strange error in Qlikview web version which gives an "unexpected exception occured"on a few sheets in the document.
We browsed through some of the articles in the community and there was a solution which someone posted to delete and recreate current selection box in all the sheets. We did that but still no luck.
Are only a few sheets within the app, but the rest displays OK, or you cannot see anything at all from that app?
Also, does that happen to any user or only to specific users?
Depending on the answer to those questions, I'd check whether the object is too big to be calculated given the selections, or remove the .Shared file altogether if it works OK opening for the same user in a different browser.
