Steps to Reproduce:
In the federated properties test system, load Special:RecentChanges and change the filter from 7 days (default) to any other number of days.
Actual Results:
When the results filters are changed, an error is displayed (see screenshot). Refreshing the page results in the recent changes displaying properly.
Expected Results:
Changing the filters (tags, number of results to display, timeframe) should result in the Recent Changes list updating without requiring a refresh of the page.
