fshaharyar on "Plugin Upgrade"

Hi All,

I am new to wordpress, I have been working on a wordpress e-Commerce website.

I see notification to update the plugins on the admin. In case i do this will create any problem on the website.

Like
1. will effect the design of the custom template.
2. making any custom function not work properly.

Thanks in Advance.
