I seem to be having problems with the plugin (2.0) since upgrading to WP 3.8.3. The problem happens after avatar upload - the upload does not complete and the page reloads but stalls before loading the full page HTML (this results in whitespace from half way down my page onwards).
Then when I visit the User section in WP admin, only a handful of users show up in the list yet the total user count (100s) is about right.
If I disable the plugin, the problem is resolved. Anyone else seeing this after upgrading to WP 3.8.3?
