Hi , We setup new environment and able to open all tabs in designer u

Since it is working in Chrome, it sounds like this is not an issue with the environment itself. Can you try clearing the IE cache? (Ensure 'preserve favorites website data' is unchecked.)

Thanks for the Response Tom . I did it but i don't see any change. If i login with xxx/suite/designer i'll not get this error but if i login as a tempo first and later change to designer then i get this error.

Can you record a short video showing the steps you take to reproduce this behavior (you can use a free tool like www.techsmith.com/jing.html ). If not, let me know the steps you took to reproduce.

1) Example URls:- xxx.com/suite/designer and xxx.com/suite/tempo
2) First used xxx.com/suite/designer --> Login and able to navigate processes tab without any interruption.
3) Second time used xxx.com/suite/tempo --> login and changed the url to xxx.com/suite/designer view and i got this error.
4) Just now got to know , by repeating same steps in Chrome i'm having this problem.

if i follow same steps , i'm able to recreate this issue in both the browsers.

1. What version of Appian is this?
2. Can you attach the latest application server log?

We are using 7.11 and Please find the attachment

server.log

Sorry , that is old one.. here is the latest one

server.log

Are you using a webserver? If so, check that the static content is up to date.

Is it possible for you to record a network capture using a tool like Fiddler or the IE developer tools and attach it?

Static content is up to date. latest hotfix is also deployed. I'll try to record network capture.
