Hi, when I installed and ran your plugin on my site, my posts suddenly became all "uncategorized" and showed no tags. When I uninstalled the plugin, all the categories and tags showed up, but only half of the posts (over 1,000 total) showed their categories. The rest are still uncategorized. I searched online and tried several solutions: restarting the server, deactivating all plugins and reactivating one-by-one, etc. Nothing worked. I have to either restore the database or manually re-assign the categories and tags for about 500 posts. Please be aware users, and please fix developer. Thanks.
