Hello everybody, I successfully upgraded to Dolibarr 4.0.2 from 3.9.2, everything is working fine as of now.
The only problem I got was that, in the import dialog, I couldn’t get after the selection of the import type as the option to choose the filetype was not shown. In the error log from Nginx I found:
2016/11/17 15:26:51 [error] 31971#31971: *2091 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught PHPExcel_Exception: Multibyte function overloading in PHP must be disabled for string functions (2). in /home/mysite/sites/dolibarr/htdocs/includes/phpoffice/phpexcel/Classes/PHPExcel/Autoloader.php:34
