Train as Good/Spam not an active function in menu

I’ve been using SpamSieve for a long time. Many years in fact. It always worked as advertised. It worked so reliably that I only recently found that the functions to train as good/spam wasn’t shown in black bold letters anymore in the menu but in grey ones. Also, the shortcut keys didn’t work anymore. I can select the function ‘SpamSieve - Change Settings,’ but the two functions below are not selectable anymore. Tried reinstalling the plug-in to no avail. Any ideas how to resolve the problem?

I’ve never heard of that happening before. Which version of Mac OS X are you using? Which version of SpamSieve?

Please check the folders:

/Users/<username>/Library/Mail/Bundles
/Library/Mail/Bundles

Are there any .mailbundle files there besides SpamSieve?

We’re not exactly sure what happened, but after a couple days and restarts it’s back to normal.
