My tags are all gone!

This may happen when you switch the taxonomy for this plugin. Whenever you switch to a new taxonomy (for examply your 'post tags', that taxonomy will be completely replaced. Likewise, the old taxonomy will be completedly cleared. Moving back and forth between taxonomies therefore may have the result that your tags are all removed... This is by design.

To prevent deletetion of your tags you can do two things:

1. Keep using the newly created taxonomy "Words". Most WordPress taxonomy related functions like wp_tag_cloud() have an option to select a specific taxonomy. This allows you to use both your old tags and the new word taxonomy (e.g. to create tag_clouds).
2. Make a backup before you start using this plugin in combination with your post tags.

Can I get back my old tags?

This plugin provides no mechanism to restore your old tags. If you decide to use this plugin to set your post tags it may be wise to do a backup first...
