Every so often I'll get an email like this
I tried installing your extension via magento Connect on my store running Magento 220.127.116.11 but received the following error:
CONNECT ERROR: Package file is invalid Invalid version, should be like: x.x.x Invalid stability Invalid channel URL Empty authors section Empty package contents section
A Magento user tried installing one of my extensions, but Magento Connect has failed for some reason. This, despite my being able to install the package locally without issue. It's usually a network related problem on their end, or a hacked core, and is occasionally the dreaded "that file extracted as a folder" issue, but is always something out of my control.
Where should I send users for support with this sort of thing?
