Plugin incompatibility conundrum

Hi guys, earlier this week, I was informed by the users of my Socialize Me! Plugin that it no longer works with WordPress 2.7.x

I’ve been onto the Creating Options page and gone through all of the recommendations.

However, when I go to the Settings page for my Plugin and then update a field with a new value, I get sent to the “All Settings” page.

There’s something obvious not right somewhere, but I just can’t figure out what I might have missed out, or got wrong.

I’m using the get_option() function, but now it seems there’s all kinds of crap I’ve got to do to tell WordPress which fields are being updated, which seems more a hindrance than a help.

Because of the way the Plugin works, and because I have the Plugin split across two classes / documents, there’s no sensible way of knowing which fields might be in use and which might not. But that’s another issue, perhaps.

Any ideas?
