Theme is not getting changed in NWBC 5.0

Hi Experts,

I have a problem in THEME and BRANDING_IMAGE in NWBC 5.0.

I am using NWBC 5.0 PL2

Problem is the theme is not getting changed /reflecting after updating in the Config parameters table.

  I have added the following Config Parameters in the '/UI2/NWBC_CFG_CUST' table.

BRANDING_IMAGE

BRANDING_URL

WELCOME_MESSAGE

THEME

USE_BROWSER_CACHE

I have appended the '/sap/bc/ui2/nwbc' path in the server URL.

Unfortunately,  the BRANDING_IMAGE and THEME are not reflecting in the NWBC, and other parameters are reflecting in NWBC and they are working.

Could some one help me any other configuration is missing or some thing wrong.

Thanks in advance.

Naveen.
