When using class PHP_XLSXWriter LINK on Linux system I always get this error opening the file in Excel:
Parte rimossa: Parte /xl/sharedStrings.xml con errore XML. (Stringhe)
(Part removed: Part /xl/sharedStrings.xml with error XML. (Strings))
Carattere xml non valido. Riga 2, colonna 1898.
(xml char not valid. Row 2, column 1898.)
Record rimossi: Informazioni cella dalla parte /xl/worksheets/sheet1.xml
(Record removed: cells informations from part /xl/worksheets/sheet1.xml)
On Windows PHP Apache no errors, no problems! I have no idea how to solve the problem...
Any help is much appreciated!!!
