button no show

This looks like a problem with the theme. What theme are you using?

BTW: Also note that the buttons automatically hide in desktop browsers after a few seconds and show again as soon as you move the mouse.

Hi, you can check : https://phumyhung.vn/urbanhill/phong-su-anh-su-kien-ra-mat-du-an-urban-hill/

I will check this and will let you know, when I found a problem.

Ok, it seems you created some CSS rules for BUTTON elements. However, Lightbox with Photoswipe also uses BUTTON elements to display the controls.

Please check you CSS – you must not add rules which apply to BUTTON elements globally without specific selectors.

Thanks Arno Welzel, now it working

Thanks for your feedback. I’m happy, that it works now.
