Hi, I have a problem with ad-buttons plugin (http://wordpress.org/extend/plugins/ad-buttons/). It stopped working. Doesn't appear on the page (should be in the sidebar) - http://www.pawelsuder.pl/referencje/. Doesn't appear in the list of plugins. But options bbookmark is available in the dashboard. I deleted the folder manually from the server and 2 SQL tables but after adding back the plugin remembers my settings and the problem is still on. How can I permanently remove it to be able to upload again and fix it?
