* Have to work correctly immediately: http://beta/?feed=wpbm-ics |
| 26 |
* Nice looking link: http://beta/feed/wpbm-ics -- require to update permalink structure at WordPress > Settings > Permalink Settings page by clicking on "Save changes" button. |
| 27 |
* Finally, to display your feed, you’ll first need to flush your WordPress rewrite rules. |
| 28 |
* The easiest way to do this is by logging in to the WordPress admin, and clicking Settings -> Permalinks. |
| 29 |
* Once here, just click Save Changes, which will flush the rewrite rules. |
| 30 |
* |
| 31 |
