I installed a network, so far everything was working (it is not the firts time I do this), but when I go to add a site it tells me “that the adress is not valid or non-existing”
Any clue what is going on, I have put the code as described in the instruction in my config and htaccess files.
It seem to be asking me for a sub-domain, but I wanted a sub folder. I am writing http://www.groupeespaces.ca/en but it is written just below .groupeespaces.ca as if wanting me to create en.groupeespaces.ca
When I installed the network a message said that my install was not recent and that my wordpress network sites should use sub-domain and it could break the link to my images. I don't know how to resolve that either and why it gave me that message.
I guess I found my answer here : You cannot choose Sub-directory Install (for a path-based network) if your existing WordPress installation has been set up for more than a month, due to issues with existing permalinks. (This problem will be fixed in a future version. See Switching network types for more information.)
So it brings me to another question : what is the implications for me to use a sub.domain instead of a sub/directories. Is it a problem with SEO ? Will it be working with my plugins Multisite language switcher ? I am use to doing it with sub/directories and not with sub.domain. See for example my own site at http://www.juliecloutier.com where I created the main site on the root and used language switcher plugin to navigate to the french version of the site in the sub/directory http://www.juliecloutier.com/fr/
