NIP 2014.6.4.11 disabled or enabled change layout of a site.

Norton Identity Protection 2014.6.4.11 for Google Chrome v 32.0.1700.107 m  influenced the correct representation of a site I often use if  the extention NIP is enabled.

If the extension NIP 2014.6.4.11 is disabled everything works perfectly again.
I am using Windows 8.1 64-bit and Norton Internet Security v 21.1.0.18
Is there a solution for this problem?

Thanks for any help.
