Hi,

I'm using api.php for a long time (with bot account), but for last 2-3 weeks instead of usual login response my bot has the following message:

<?xml version="1.0" encoding="utf-8"?><api><error code="internal_api_error_MWException" info="Exception Caught: Internal error in ApiLogin::execute: Unhandled case value">
