My items stop selling suddenly.

I'm new to ebay. I started selling in August 2013. My items were selling ok but suddenly this week I have no sale and no view count. Paypal has ask me to provide identity verification which I have not provided yet. Will this affect my sales? I am selling gift and decoration items and this week I added industrial products. Just wondering if because of PayPal and adding items of very different category effect my sale? Please suggest
