I made a video for the group on WordPress. WP changes all the time which is quite frustrating. In my longish experience with WP most people’s problems can be solved by checking out the publication status (have they verified their account? Update the site, publish and refresh) and checking the theme/template they use. Does the theme support what they want? Can it be edited to do this?
Well those and what is a page/post. The frustrating part of supporting WP is then that each theme is very different and has a different of affordances and features. A general rule would require telling everyone exactly what theme they have to use which minimises the customisability of the site and its reflecion of the person.
