But what I wrote on the page is:

Is there another header (....)

No

Check space problems

Check space problems

There is no exception in the space. it is normal to use Firefox and IE to open it.

I opened it with Firefox and downloaded it.

No, it's normal for me to open it with Firefox.

It is generally a space issue. For example, space does not support php

Isn't your space server set to support php?

Yes. it used to be good. it started to go wrong from yesterday.

Either you or someone else modifies the web service configuration.

Ah ......

Why can I open it normally in ie Firefox and other browsers?

Modify the header file

Content-Type: text/html;

Check if the keyboard is down. Ctrl or alt

Strange problem

In this case, it is generally a keyboard problem. The correct solution is on the 19 th floor.

Turn off chrome and open it again.
