Version: 24.11.01.000 In the "Share usage statistics" page (/admin/usage_statistics.tt), I get: The value of your system preference 'UsageStatsCountry' is not valid (Selected Country Name). Please select a valid one. Also, the selection doesn't default to the saved value. Adding ".trim" on line 103 where it compares the saved value to the one in the loop for generating the options fixes it for me. No more message, and the default selected is what was saved.
