SG500 Web interface - Unable to display Port settings page

[tomas.skocdopole]

Hello,

I have problem with my Cisco SG500-28. I try flash newest firmware and boot code (actually there is the latest versions), but this does not resolve this issue.

Software Information
Firmware Version (Active Image):	1.4.7.6
Firmware MD5 Checksum (Active Image):	55fd7c3feff273d788634b71581ef79a
Firmware Version (Non-active):	1.4.1.3
Firmware MD5 Checksum (Non-active):	f73388df555545d4ac56b89a208493c9
Boot Version:	1.4.0.02
Boot MD5 Checksum:	accbdaec117726d0e5149babc5b2a0b0

When i click Port Settings page, the page is displayed as shown this screenshot.

Other pages are normally working without problems.

Where should be problem?

Thanks for help

Regards Tomas Skocdopole

Silly question, but have you tried a different browser.  There has never really been a Cisco management GUI that didn't have browser caveats.

Yes, I tried Chrome, IE and also opened it from another computer. Always the same.
