It appears this is an incomplete function added before it was ready, clearly evident if you hit the license link.

Until they sort it out locate this line at the bottom (-ish) of product-grid-functions.php and comment it out as shown.

//add_action('admin_notices', 'product_grid_admin_notices');

Doesn’t appear to affect functionality, yet.

Just updated to 2.10.3, I still see

function cycloneslider_service_zip_archive( $plugin ){
    return 'ZipArchive';
}

Which should check if the class exists . . . but previous users who don’t have Zip compiled have reported 2.10.2 fixed it, so you’re probably addressing it in another way . . . all good. 😛

I think you misunderstand the logic . . . look . . . .

The original: something somewhere (we don’t care what) calls the function cycloneslider_service_zip_archive and it originally just assumes the class exists and returns an instance of the object.

function cycloneslider_service_zip_archive( $plugin ){
	return new ZipArchive;
}

That is the source of the error if the class isn’t compiled with PHP. what the below code does says “only return the class if it DOES exist.” The advantage is that if the Zip class does get installed it will work normally. (Note I’ve added the extra “return” line I mentioned.)

function cycloneslider_service_zip_archive( $plugin ){
	if (class_exists('ZipArchive')) {
		return new ZipArchive;
	}
	return null;
}

Line 1: Call the function to **attempt** to include ZipArchive
Line 2: Ask PHP to see if this class exists
Line 3: If it does, return instance of the object.
Line 4: end of logic block; if it has returned it will go no further.
Line 5, If the Zip class is not installed, as in your case, lines 2-4 are skipped and NOW we return null; there is no ZipArchive object.

What you’ve done there is return null in any case, which is the same as commenting it out:

function cycloneslider_service_zip_archive( $plugin ){
	// return new ZipArchive;
}

For a quick fix, comment out line 403 In cyclone-slider.php as below

I know this is an old post, I encountered this slider with a theme (that I’m on my third week of cleaning up) and got to this issue. Surprised it’s still going on.

Just an FYI, the half correct way to remove the code that includes the ZipArchive class is to change line 403 to this:

function cycloneslider_service_zip_archive( $plugin ){
	if (class_exists('ZipArchive')) {
		return new ZipArchive;
	}
}

That way if the class exists it will still function.

The fully correct way would be to throw an exception and inform the user what is actually wrong so they can install the extension. I don’t think I’ll put that much work into it, I’ll just recompile PHP and be done with it. 🙂
