The is the first time I have used multi site so please be patient
On attempting to install I get :-
Downloading install package from http://wordpress.org/extend/themes/download/summ.1.0.6.zip…
Unpacking the package…
Could not create directory. /httpdocs/wp-content/upgrade/summ.tmp
So do I have to install via FTP and if so is it to the usual directory wp-content/themes ?
