Why when I connect to the PRTG server using a hostname is AJAX not available?

Votes:

0

When I browse to the PRTG server using IE (version 8.0.7601.17514) using the server's host name, the AJAX interface is not selectable. The login screen says that "My browser is not supported". However, when I browse to the server using its IP address, I CAN select the AJAX interface. Why is that?

Hello,

IE 8 and IE9 have the "Compatibility View" option. If this option is activated the ajax view in PRTG is not supported.

We will be putting a header into the HTML which causes the compatibility view to be killed.

If you want to do this by your own right now, please find htmlheader_mini.htm in the includes folder in your PRTG program folder and paste this code below the <head> tag:

<#system type="browserdependent" browsertype="MSIE" version="8" browsercontent="<meta http-equiv='X-UA-Compatible' content='IE=8' />"> <#system type="browserdependent" browsertype="MSIE" version="7" browsercontent="<meta http-equiv='X-UA-Compatible' content='IE=8' />"> <#system type="browserdependent" browsertype="MSIE" version="9" browsercontent="<meta http-equiv='X-UA-Compatible' content='IE=9' />">

additional Information:

If a website is opened with compatibility view once IE remembers this setting and opens the site the next time automatically in compatibility view. To check if your website name is listed in the compatibility view list please open the menu in IE, go to "Tools->Compatibility View Settings" and check if your host name is in there. Remove your host name and you should get the normal behavior.

Best regards

Hello,

that should not come from PRTG, in anyway, please consider upgrading to IE9 or use Firefox or Chrome.

Best Regards.

This behavior is caused by the fact that IE9 by default shows intranet sites in compatibility view.

To change this behavior follow the steps below:

  • 1. Right click the header of your IE9 window and enable the command bar.
  • 2. Navigate to menu item "Page/Compatibility view settings"
  • 3. Uncheck the "Display intranet sites in Compatibility View" checkbox

The AJAX GUI option immediately comes available now.
