Norton safe site icons missing

Hello everybody!

 

Unfortunately there's no folder "exts" or "extensions" or anything like that?! I made all folders and files visible, even secured system files.

 

Using NIS (should be 2012, but not sure. I can't even look it up, because the contract with my ISP has ended) version 18.7.2.3.

Can anybody help me please?

 

Thanks in advance, kind regards,

 

Stefan
