When I try to write a file to Excel, I get an error that the headers can not be modified. This is preventing my file from being created. When I switch to write a XML file it works fine. What is wrong with the excel setup?
Warning: Cannot modify header information dwzExport/ExcelExport.php on line 297 Warning: Cannot modify header information dwzExport/ExcelExport.php on line 298 Warning: Cannot modify header information dwzExport/ExcelExport.php on line 299
