RAMP accessibility issues

Hello again.

I had another look and the number of errors is greatly reduced, many thanks @awesomerobot and others who have helped!

I still get the following errors:

  • Visiting a category: Empty button on the following code:
    • <button name="Filter by: [missing %{name} value]" role="combobox" data-name="regular" data-value="1" aria-expanded="false" aria-haspopup="menu" aria-owns="ember41-body" tabindex="0" id="ember41-header" class="select-kit-header single-select-header btn-default dropdown-select-box-header btn no-text btn-icon ember-view" type="button">
    • Also on other pages with different numerals after ember.
  • Visiting a category: Empty table header:
    • <th data-sort-order="posters" class="posters" aria-label="Posters"></th>
  • Post by user “system”: Linked image missing alternative text:
    • <img alt="" src="/user_avatar/ramp-forums.epcc.ed.ac.uk/system/90/1_2.png" class="avatar" width="45" height="45">
  • Any post: Empty link
    • <a href="" aria-hidden="true" tabindex="-1" class="tabLoc"></a>
    • And permutations of the elements in the above statement
  • Search with valid results: Empty heading
    • <h3 class="search-footer"><!----></h3> (I edited the formatting here, deleting whitespace and line feeds)
  • Search with valid results: Five missing form labels on the advanced search (I can provide more info if needed)

Any help will be most appreciated.
