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"> #0 /usr/local/apache/common-local/php-1.5/includes/api/ApiBase.php(686): wfDebugDieBacktrace('Internal error ...') #1 /usr/local/apache/common-local/php-1.5/includes/api/ApiLogin.php(143): ApiBase::dieDebug('ApiLogin::execu...', 'Unhandled case ...') #2 /usr/local/apache/common-local/php-1.5/includes/api/ApiMain.php(412): ApiLogin-&gt;execute() #3 /usr/local/apache/common-local/php-1.5/includes/api/ApiMain.php(253): ApiMain-&gt;executeAction() #4 /usr/local/apache/common-local/php-1.5/includes/api/ApiMain.php(237): ApiMain-&gt;executeActionWithErrorHandling() #5 /usr/local/apache/common-local/php-1.5/api.php(77): ApiMain-&gt;execute() #6 /usr/local/apache/common-local/live-1.5/api.php(3): require('/usr/local/apac...') #7 {main} </error></api> (ru.wikipedia.org, login:Secretary, user account groups: autoconfirmed, bots) In 20% of cases login success. Can anyone help me to resolve this issue? -- Sergey Vladimirov
