iRules Data Group List : No Access

Hi All,

 

I've just upgrade my BIG-IP for about one month ago, from v10 into v 11.5.3. After upgrading, all system was running well without any user complain.

 

But today, i've just realise that I had a problem when trying to open data group list. Everytime I try to open data group, the result show "no access". I already tried to create a new data group list, an when I try to open it it shown the same "no access" result. Below the capture:

 

 

Did anybody ever met a problem like this before? And what is the solution for this?

 

Thanks before for your help..

 

regards, Ahmad
