  3. Extract the files.
  4. Optional: Copy q2apro-popular-questions-lang-default.php to a new file and add your language, e.g. q2apro-popular-questions-lang-fr.php
  5. Upload the files to a subfolder called q2apro-popular-questions-widget inside the qa-plugin folder of your Q2A installation.
  6. Navigate to your site, go to Admin -> Plugins. Check if the plugin "q2apro Popular questions widget" is listed.
  7. Navigate to yourq2asite.com/admin/layout/ and add the widget to your layout.

Update to v0.2:

Instead of daily the cache update takes place hourly, see new admin option.

Also new: Admin can decide if the answer count is shown or not:

Q2A version: 1.7

I just realize that it could be that question title gets edited and changes. The cached data would still show the older question title. Maybe a minor issue, but an issue that could be solved by an event listener for the q_edit event.

Plus, the answer count would also need to be updated on answer events. But I prefer to not display the answer count (or give it an admin option to show the cached answer count).

I also think of a not daily update but maybe hourly or x hourly (admin option) for the cache, that would make the data more accurate.
I have updated the plugin as described above in the question.
