When saving the page is staying blank.

The custom report is create but does not work.

So we need to take a allready made report and to make changes on it.

I also notice that when editing the allready made report, changes work but filters disappears, so if I have to make a second editing that's not clear.

Update : it seems that the problem is bigger on Google Chrome. On Firefox I find back filters, but with custom reports no way to find any data, even if no filter.
