First, i have to thanks all people behind this proyect.
But, here is my problem: i can't open any file generated by PHPExcel with .xlsx format. I tried the test's examples, and i got this message on Excel:
First message: http://i30.tinypic.com/2hftcn9.jpg
Second message: http://i30.tinypic.com/oucvf8.jpg
When i run the script, i don't have any error or warning message:
19:43:14 Create new PHPExcel object
19:43:14 Set properties
19:43:14 Add some data
19:43:14 Rename sheet
19:43:14 Write to Excel2007 format
19:43:14 Peak memory usage: 7.25 MB
19:43:14 Done writing file.
.xls format work great.
Any idea what is the problem?
