On prem EAC shows in text only

[allanw-trillium]

Hi All

I'm hoping someone has seen this before.

EAC is only showing in text only on both IE11 and Chrome. I've rebooted the server, etc. and it's still happening. 

Everything was working fine up until last week. 

Any ideas?

Looks like an issue with the Updates.

Bring the OS to the latest security and patches - restart the server.. should fix your issue.

It could be your browser cache or your site being assigned to the wrong zone (intranet, internet, trusted etc.) in IE.

Also the recycle of the ECP app pool could solve your problem.
This refreshes the ECP virtual dir.

我也碰到上面问题，最终解决办法如下

1. Open the Group Policy editor (gpedit.msc) and go to Computer Configuration\Administrative Templates\System\Mitigation Options\Untrusted Font Blocking.

2. Click Enabled to turn on the feature, and then click one of the following Mitigation Options:

   • Log events without blocking untrusted fonts. Turns on the feature, logging installation attempts to the event log, but not blocking untrusted fonts.

3. Click OK.
