Question

我正在通过升级向导将Sugar实例从当前版本6.3.1升级到6.4.6，我可以成功完成系统检查的第一步，但是当我继续上传升级包时屏幕空白。我确保memory_limit和max_execution_time在php.ini中是合适的，但这也没有帮助。升级向导日志也没有帮助，它只是说：

根据blog，我将php.ini中的设置修改为：

max_execution_time = 14400 
max_input_time = 14400 
memory_limit = 768M 
post_max_size = 128M 
upload_max_filesize = 128M

但我仍然得到空白屏幕。我尝试重新启动服务器，但这也没有帮助。知道什么可能是错的吗？

空白屏幕通常是致命PHP错误的迹象，因此您应首先检查您的php和Web服务器日志以获取更多信息。

升级向导中的上载升级包屏幕为空白
