(Let me know if you are not sure how to do this, but it is found in the project settings. Then check what the log says (if you have enabled logging). If not, set a breakpoint in the app_error_handler to see what the err_code, line_num and file_name is. It should point to an APP_ERROR_CHECK(err_code). So what is the value of err_code, and what function returned this value?</p> <p></p> <p>BR,</p> <p>Edvin</p><div style="clear:both;"></div>
