When I try to install an extension I get the following message
The path /var/folders/cc/3vcync0j7n7268j23slgb2dc0000gn/T/TemporaryItems/(Un documento siendo guardado por PopClip)/Append.popclipext does not contain a valid PopClip extension.
Reason: Could not load Config.plist. The XML may be malformed.
what can i do?
