Thanks for answering so fast.
Sorry, it was my mistake. I am extending the plugin for my own purporses.
The original plugin (v6.3) is working very well on WordPress 3.1.3 with network enabled on a production enviroment with more than 150 subblogs.
Thanks all for the help.
Cheers from Barcelona.
I have WordPress 3.1.3 with Network enabled.
I have subscribe2 plugin v6.3.
I can’t “network activate” the subscribe2 plugin. It doesn’t work.
I will try plugin-commander.
