I have a friend's 3 sites all set up with a single plugin folder in their main domain and their 2 other sites connected via a symbolic link.
This is mainly as their sites share mostly the same plugins, so it saves on admin (my time) and they only have to update stuff once to replicate over their 3 sites.
Problem I has is that it doen't work with this plugin. It works with all other plugins on there and I cant think why it wouldn't work for this one too?
The Settings area shows a list of the buttons as text rather than the buttons in their rows. Looks like the Java is broken?
On editing a post/page it looks like the slightly enhanced editor.
If I jiggle stuff arond so that I can set it up in the Settings area, then revert it back to the symbolic link, the edit post/page editor is blank ... no buttons nothing.
Could be a problem with Multi-Site too, but I've never used that so I can't comment
Any help/advise welcome
