I have defined some sidebar widgets in the functions.php of my theme - and somehow, I cannot recall at what point exactly, I ended up with those custom defined widgets appearing twice in the Appearance - Widgets Admin Panel.
I believe, I need to clean out my database tables, and also suppose that it is the table wp_options that I should be looking at. But I don't have a clue where and how to find those duplicates. Where it says widgets_something, it is all cryptic numbers.
Can anybody enlighten me, or point to a source on the Net, where I can read up on this subject: how are custom sidebar widgets stored in the database tables of WordPress?
