Hi mErRYo,
can you verify whether any reports are present in your reports directory?
by default this is
/reports/ in your dspace install dir
https://github.com/DSpace/DSpace/blob/master/dspace/config/dspace.cfg#L1439
Just a wild theory at this point but if the directory is empty, it could be
that this line already sends you to a no-report page
https://github.com/DSpace/DSpace/blob/master/dspace-jspui/src/main/java/org/dspace/app/webui/servlet/StatisticsServlet.java#L168
while the code still gets down to another forward on line 260
https://github.com/DSpace/DSpace/blob/master/dspace-jspui/src/main/java/org/dspace/app/webui/servlet/StatisticsServlet.java#L260
At this second forward, he can't forward you anymore because you have
already been forwarded, hence the error.
Can't explain it otherwise because I only see two forwards in that servlet.
this bug could be fixed by adding a return statement on line 169.
