I have been running 1.7 on the site I’m testing for weeks and it seems like it hasn’t been a problem for the whole life of 1.7 as some users are fine and other users haven’t been able to activate at a later date.
Unfortunately I don’t know how to find out any sort of timeline for when this broke.
Thanks Paul. I’ve made the change in the plugin PHP and it’s had the desired effect of making it activatable on a per site basis. Problem now is that I can’t find the moderation menu in either the individual blog dashboard or the network dash. Thanks for your help, I guess you win some, you lose some.
