Hi, I've a similar problem when I try to install MJ.
The extension manager won't upload the zip file form my PC
So with Filezilla, I have copied the unziped contain to a tmp dir on my server (
www.my_site.fr/MJ)
Now the manager says that he can't copy "index.html" from ../MJ to components/com_mobilejoomla
* JFTP::store: Bad response
* JInstaller::install: Echec lors de la copie du fichier : ../MJ/index.html vers /htdocs/public/www/components/com_mobilejoomla/index.html
Before this he have said that he cant create the com_mobilejoomla directory, so I have created it with Filezilla
I try also to set 0777 attribute on this dir but same issue.
Thanks
