after facing the "Parameter _reportName cannot be null or empty".error two times i tried to compile all classes. the compilation process was interrupted and SSRS reports are not working ..
tried full application compilation axbulid.exe
renamed xppl file
full cil compile. , with one Aos service running, (got some warnings )
restarted sql reporting services
flushed the cache . and reset data usage
the reports opened but could not fetch data .
then someone suggested that I synchronize database so I did.
then I tried to rebuild and deploy the reports and after deployment, the "Parameter _reportName cannot be null or empty" error showed again .. then I decided to compile all classes mentioned in the error message and deploy the report again ...
the result is now i have duplicated date parameter (from -to date ) .
what should I do . can I restore specific reports from DB backup?

I have the same question (0)problem solved .. stopped all services then i rebooted all 3 Aos servers (not simultaneously - one by one ) .. restarted sqlreporting services
and everything worked well after that
