Thanks Calin!

Worked, thanks.

Mersi Anamaria,
I will test it.

It was from general setting of the theme… sorry.

Yoast plugin made this. So no need support on this task.

Already solved the problem by using revolution slider : https://cadarmarius.ro/ – this was the link of the website. But you can check arredoannunci website, as his website is exactly the same on mobile. Thanks.

And on mobile there is another problem, sometimes i get blank image in slider while i navigate trough slides.

@media (max-width: 500px){.iosSlider-col-3 .td_module_slide .td-module-thumb, .iosSlider-col-3 .td_module_slide .entry-thumb {height: 120%;}}

I addded } at the end because it was giving an error, but still no change.

Is on 3 columns and not work, same thing in your exmaple, the one in 3 columns is with the height lower and the image has unnatural look. Just resize the browser and see. so i think slider has some problems.

It was cache problem, because i changed in setting to show my full name, now it looks ok.

Is a great theme, but we are forced to use 3rd party plugins for make the website faster. I disabled wp-rocket and yoast and was the same thing. I will try to debug more.

Ok, adding that size and 70×50 for sidebar where i sawed Td_218x150 fixed the thumbnail problem.

Can You check my slider from homepage? Full is ok, but on resize is meesing with the image aspect ratio. The height is lower and looks strange.

Ok, just found the problem, i used right click to check, but after inspect element i realized that there is another size to :

324×160
