Recently did firmware updates of 20 Routers 2830/2850 mainly. Although i thought all had gone well we cannot access the WAN > Internet Access > Details Page and just get this message.

HTTP/1.0 500 Server Error !!! Pragma: no-cache Content-type: text/html WWW-Authenticate: No handle used
500 Server Error !!!The server encountered an internal error or misconfiguration and was unable to complete your request.

I presume now i will have to do a full reset of all routers and reconfigure to put right. This is not practical as the sites are all over country ! Anyone else having issues ?

Just a follow up. Just reset a test unit to factory and all is OK.
However when i restore the backup config file the WAN > Internet Access > Details Page does not work still.
It looks like i will have to manually reset & configure every router !
Once again annoyed with the config file restores which does not always work.

The problem may come back if turn off ipv6.Is a bug with latest firmware but how ever changing firmwares versions, it needs always the rst file.Thanks
