在 magento 站点中,我无法访问管理面板。
当我使用管理面板时,它会在火灾错误中显示错误:
"NetworkError: 500 Internal Server Error - http://192.168.1.100/magento_upgrade/admin"
The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must to be declared in the document or in the transfer protocol.
我该如何解决这个问题?
