Well my problem is this after fix wordpress asking me for FTP user and password doing this: Wordpress asking for my FTP credentials to install plugins
Wordpress no longer asking me for FTP user and password but surprise to me I have another error this one it said after downloading the update for the plugin: Could not create the directory
I don't know if this normal after fixing the FTP on that way or if this can be fix. Another important thing is that I was doing this in a localhost just for learn how to use wordpress
