推荐答案
所有权限均已正确分配，
但它仍无法正常工作.
All permissions are assigned properly ,
but it is not working yet.
将其部署到另一台计算机时是否有问题?我想你是说这是问题.
如果它在本地运行，请确保在目标部署环境中，Web服务器所运行的帐户在您的数据目录中具有读/写权限.
干杯.
Do you have a problem when you deploy it to another machine? I think you''re saying this is the problem.
If it works locally, make sure the account that the web server runs under has read/write permission in your data directory in the target deployment environment.
Cheers.
