The pictures in the sliders cannot been seen on smart phone

The pictures in the sliders can been seen on PC, but cannot been seen on smart phone.
I just know the wordpress has been updated automatically.
I cleared the cache, but it didn’t help.
My website is built on Bluehost and it is ‘www.atmax-tech.com’.
Please help.

Is there any one can help me?

Hello there,

I would like to apologize in advance for the delay.

To make the slide image becomes responsive on smaller screen, from dashboard, go to Appearance > Customize > Header area > Header Slider > scroll down until you find the option that says “Slider mobile behavior” and then enable responsive.

Dear Mr. Kharis,

I did it before.
I have tried many ways to fix this problem.

Now, I deactivated WP Super Cache, it didn’t help.

Please help me to find out the problem.

Hello there,

Please check the inc/slider.php file. Does it look like this?

Dear Mr. Kharis,

You guessed right.
The problem is from slider.php.
Your other code is like…

    $slider_title_1     = get_theme_mod('slider_title_1', 'Welcome to Sydney');
    $slider_title_2     = get_theme_mod('slider_title_2', 'Ready to begin your journey?');
    $slider_title_3     = get_theme_mod('slider_title_3');
    $slider_title_4     = get_theme_mod('slider_title_4');
    $slider_title_5     = get_theme_mod('slider_title_5');

It is not correct, I think.

Problem solved.
Thank you so much.

Best regards,
