Cannot read profiles directory problem – 1.5.3.9 version

Hy!

I installed your plugin and activated, but when I click “Scan now”, I get this message:

Cannot read profiles directory

I have “profiles'” folder here: XYZ.com/wp-content/uploads/profiles . The “profiles” and the “uploads” folder are have 777 permission.

But I get “Cannot read profiles directory” message. Do you have any idea, why?

I have another one hosting package in this same server, whit WP 4.4.2, and the P3 run well and makes results, but the profiles and uploads folder are have 755 permisson.
