Working on magento community 1.9.1, security patch up to date.
I've tried to install an extension, but I get this error message :
> Checking dependencies of packages Package core/Mage_Catalog failed: > Channel 'core' doesn't exist Installing package > community/Package_name_version Package community/Package_name_version > installed successfully Package installed: community > Package_name_version
I have tried the following base on what I found on the net, which is really not a lot about this issue...
> ./mage mage-setup
Then add the extension again via magento connect & Then delete /downloader/cache.cfg
This had no result.
It's not comming from the extension because it's working fine on another instance of magento. The extension seems to be installed, but when I try to use it under the admin panel, i get this error :
Error: Http code "302" returned from extension_name
Thank you for helping
