Twice today, I have found large segments of my hierarchical menu disappearing. I have re-adding several segments only to find them disappearing again. Any clues about resolving the problem. More background that may be relevant: Before the problem started, I noticed that the URL for a page did not match the Custom Menu structure that I had created (there was an additional page name in the path). I thought... it would be a good idea to create a new page with the appropriate Parent page, then copy the content of the previous page and paste it into the new page. Apparently this was not a good idea. In any case, if there are tips on creating a Custom Menu with the Twenty Twelve theme, I would appreciate those tips. I am having some concerns about continuing to use the Twenty Twelve theme.
The blog I need help with is blog.uvtaxonomy.com.
