Forwarder debug
First of all connect to the emonWRT with SSH. Use [Putty | http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe] program if you are on windows. Just open a terminal in Linux.
For this you will need to issue the ps command to find the process number of the forwarder program:
$ ps | grep emon
From the output of this command you should see a line with /usr/bin/emonwrt_forwarder.sh. Take a note of the first number on that line (say it is 1280). It should look like:
1280 root 1536 S {emonwrt_forward} /bin/sh /usr/bin/emonwrt_forwarder.sh
then kill the process with:
$ kill 1280
Then run the process manually like so:
$ /usr/bin/emonwrt_forwarder.sh
