I reviewed the site last night and found a few things broken.
Added Search  on user page and categories page.
Added  home page from title
I could not do the date fields. The way the search bar was done was not the way I'm familiar with in order to add additional fields,
I added links on category page to add more categories or go home page
Added migration for expiration date
Login link is broken. this would be a nice feature to have
