Could you publish here content of file cache/mod_gk_weather.xml ?

I checked with one of the programmers and we´ll test soon in one of our servers. We note that because we are still in development for the new webpage, tests won´t take effect immediately because it has performed locally on the cpu. Soon we will contact again if appear any problem.

Thanks for attention.

Anyway follows the mod_gk_weather.xml:

Sorry but I need content from CACHE/mod_gk_weather.xml file You showed me module XML file

I didn´t find that one in CACHE directory.

But we solve the problem... We had problems with proxy, but now its ok.

Congratulations! The plugin is really nice! Good design and well done. GREAT!
