Fatal error: Cannot redeclare class PEAR_PackageFile_v2 ?!?
I think I have found.
the problem comes from eAccelerator and APC. When I look at my logs, when I called Magento Connect I have several errors of Fast-CGI.
when I remove Fast-CGI Magento Connect works perfectly.
I want a solution with eAccelerator and APC. If I have a solution I’ll post.
