Hi ! Thank you for your help. I did like you said but It’s not working.
Some issues which can be responsible :
– I’ve installed the plug-in for the network. Because If I deactivate it, it doesn’t show on the plug-ins list of my site.
– When activated, there’s an item in the admin menu of my site, with the page to check or not the members, group counts etc.
If I click “Save”, it says I don’t have the rights to do so. So I changed the page code to check all the checkbox by default. But it’s not working either.
If you got any other ideas to fix this, thank you very much.
