Hi! This is being caused by your theme. There are a few CSS declarations in it that are limiting the width of the element. See this screenshot for info on what they are:

Thank you for your reply. How can I change those parameters? Please guide me as I’m not an IT guy. I’ve bought a payment plugin and this problem is one of the last to launch my website.
If you go to Appearance in your WordPress admin sidebar, and then select “Customize” and then scroll down to the “Additional CSS” section in the page that loads, maybe adding something like this could fix it?
.col-lg-4 {
max-width: 100%!important;
}
.col-md-6 {
max-width: 100%!important;
}
…Probably not, though (I am still just beginning to learn how to use CSS to override theme elements), but check out this guide, which may be helpful in figuring out what you need to override: https://www.proteusthemes.com/help/customize-wordpress-site-css/
@waldymar I’m sorry, but help with CSS and theme issues is outside the scope of support that I can provide. I suggest you talk with your theme author and ask them for assistance. @hastibe provided good advice too though. 🙂
