What is this?

An image you have saved on your desktop?

No real idea, that address won't work for the rest of us. Looks like an image, maybe a moving one.

Take a screenshot (or snip) and then post here.

I don't get it it says something about a popup

It's for the Chess Mentor it says to click here on the top of the message and when I click it, it does nothing

Don't worry about it.

That's what it is

That looks like a browser security message asking if you want to allow pop-ups from Chess.com(?). Allow them, then if something happens that you don't like, turn them back off.

Though I don't know how to allow them that's the problem

Left click on the highlighted option shown in post #7.

Thanks

But after that?

I do it and nothing works

After that, everything should be peachy. I think that Chess Mentor may need pop-ups enabled. If anything occurs that is undesireable then turn pop-ups off. Without more background information I can only give you hopefully sensible and general advice.

It shows no effect though

You won't see any effect unless Chess.com needs to produce a pop-up. Go and try chess mentor, tell me if it's working correctly.

Sorry T-storm

Even after I do Chess Mentor lessons and try it still doesn't work...

I try and try but still doesn't work...
