This is okay, and is actually a case where NetSol did the right thing.
Basically, the card industry is pushing a higher security standard, and is encouraging shopping cart providers to migrate to this new standard, which NetSol had done last year.
Problem was that about 20% of users are (or were, at the time, anyway) using browsers that didn't support this new standard.
After an outcry from customers (myself included), NetSol reversed the change, which was critical, as it allowed us access to those 20% of visitors.
The card industry even realized that this was unrealistic, and they pushed back the deadline to sometime next year.
Now, with that said, you will still have browsers "warning" that this isn't the newest standard...but this is the result of some programmers somewhere that are living in their little worlds, who don't rely on e-commerce to make their living, and who don't understand the fundamentals of retail to save their lives (can you tell I don't like IT people?).
Long story short -- ignore that, be happy NetSol did what they did, and know that they'll have to make that change, along with everyone else, when the card industry-mandated deadline draws nearer.
Hope that help,
