I Founded problems when I try to convert grades to EXCEL FORMAT.
I have this message :
Warning: main(Parser.php): failed to open stream: No such file or directory in /www/netuno61/public_html/weblearning/cursos2/lib/excel/Worksheet.php on line 35
in Worksheet.php there is a statement:
require_once('Parser.php')
The Worksheet.php is part of Write_excel (a open-source code in freshmeat)
I can´t fix this bug for while.
