Not getting the EPG info in Tvheadend

Hi,

I´ve written a post in the tvheadend forum explaining the problem that I´m having, here it is...

http://tvheadend.org/boards/5/topics/22473?r=22529#message-22529

but I would like to also write here in this forum to read your opinions. This is my setup:

Tvheadend version 4.1-2195~g65dfd15 running in a QNAP NAS.
I´m using WebGrabPlus version V1.1.1/57 running also in the QNAP NAS.

This is the output of Mono version:

[~] # mono -V
Mono JIT compiler version 2.11.4 (tarball Wed Mar 26 01:48:18 PDT 2014)

        Disabled:      none
        Misc:          softdebug
        LLVM:          supported, not enabled.
        GC:            Included Boehm (with typed GC and Parallel Mark)

Could you tell me if I have anything wrong in my setup? Why I can´t get the complete EPG for all the channels?

Please find attached all the files related with WebGrabPlus in my NAS.
The script update.sh is written in crontab to be executed all the days at 07:00 and 13:00

If you need anything else just let me know.

Best regards.
