I have had it activated network wide for a while on several multisite installations and it has worked flawlessly on all sites.
Recently one site on one network ceased displaying columns for Yoast WordPress SEO plugins. All other sites display them and your plugin allows us to manage them.
It appears to be a site specific issue but I an unsure what to look for as the cause.
I already deactivated all site specific plugins and that made no difference with the issue.
I have not yet deactivated all plugins on the network, but unless you can offer suggestions for locating the issue, I guess thats next.
Any suggestions or advice will be appreciated.
