I made a big jump from 2.2 to 2.5.1 today and find a lot of interface changes, most of which I like, but I can't find the Options for Plugins in the top menu bar.
1. Log in to your WordPress administration page.
2. Click on "Plugins" in the top menu bar, and activate the "Subscription Icons" plugin by clicking on the link that says "Activate" to the right of the plugin name.
3. Click on "Options" in the top menu bar, and then click on "Subscription Icons" in the sub-menu bar. This will open up the Options screen for this plugin.
Has this moved?
