Regarding icons on http://www.softpedia.com/ , they are properly displayed in all the browsers I tested (Firefox, Opera 35, Chrome, Pale moon) but not Opera 12 even I fixed the issue I was having with other sites, which means the problem is with Opera 12 itself.
.
Now back with my issue.
I was having windows firewall disabled using "Windows 10 Toggle Tweaker", and changed the start up mode to "Disabled" in services.
What I did was changing the start up mode to manual but this only didn't work, I had to start the service manually after right clicking the windows firewall service.
.
So, enabling Windows firewall fix that, can you believe it , but I'll disable it again cause I don't like it.
It is because of MicroShit, this happen to me before, I couldn't use Windows updates (always ended with errors and nothing updated) because firewall was disabled. Also some programs that rely on "Inno VCL Styles" wasn't working and given errors like this one http://www.softpedia.com/get/Programming/Patchers/Inno-Setup-XDELTA-Patch-Maker.shtml , and I've contacted the author and he fixed that.
This is just bullshit of M$hit to force you use their firewall or maybe bad coding, and I guess I can say Opera 12 is not fully compatible with Windows 10 which could be expected (it's 2 years old now or so), other browsers have no problem with firewall disabled.
Hopefully someone can find a fix for this or a workaround of some sort.
Thank you all for your help and special thanks to @davehawley, @sgunhouse and @stng who bear with me.
