I am testing my theme with Theme Check plugin and it shows this message:
Required: This theme doesn't seem to display tags?
How can i fix this?
You need to be using one of these functions to display a list of tags associated with the post:
Otherwise the check will fail.
If you're building this theme for use with a project that doesn't need tags, don't bother adding support. If you're intending on uploading it to WordPress.org for review, then you need to add support for tags.
