When I tried to install magmi extension in my magento, i could not do it. I have install it through the upload option. But it shows the below error:
CONNECT ERROR: Package file is invalid
Invalid package name, allowed: [a-zA-Z0-9_-] chars
Invalid version, should be like: x.x.x
Invalid stability
Invalid date, should be YYYY-DD-MM
Invalid channel URL
Empty authors section
Empty package contents section
I have referred this site reference. But that is dead. The solution for this problem in this site reference1 was not helpful to me.
Already I have paste the magmi folder in Magento root folder with '777' permisiion. Help me to proceed!!
