Regarding the solution mentioned on the topic below:
Sorry, could You pls clarify what was the actual solution? Where and how should the id be added?
I have a network of 2 sites (greek main, english - subfolder) and msls is working fine at the english and it doesn't work at the main. It doesn't detect the second blog.
I have one admin user, I have both files el.mo and en_US.mo in wpcontent languages/ dir. Both languages are available in general settings.
Please, let me thank u for the great plugin.
