[lucnovales29639]

Hi,

after upgrade to IOS+web 15.2(7)E4 on WS-C2960XR-24TS-I, web base manager have some errors, missing fonts and other files, xml errors...

Text is bigger, values are incorrect and some buttons as "logout" disappears.

This problem is present using firefox (78.12.0esr (64 bits)) or brave (Version 1.27.109 Chromium: 92.0.4515.115 (Build officiel) (64 bits)).

Screenshot and console errors messages are attached.

Is there any solution ?

Thx,

Luc.

first step after upgrade is to clear the browser cache, close the browser and reopen the webinterface
according to the Release Notes for Cisco IOS Release 15.2(7)E4 - Cisco 

the supported browsers are: Internet Explorer 10.0 or 11.0, or Firefox 48.x and above with JavaScript enabled

Clearing history and cache doesn't solve this problem with Firefox 78.12.
