I import 16366 tokens from csv file.
Evenything works fine now, except when I click "display tokens" to see the list page, it is empty, the list is empty.
But I can export this list to csv file.
I find /index.php/admin/tokens/getTokens_json/surveyid/941689 returns 500 error.
But I can't find any error log about it.
In this function, it seems all data was loaded: $tokens = Tokens_dynamic::model($iSurveyId)->findAll(array("order"=>$sidx. " ". $sord));
