Can you explain in more detail the issue?

I have visited your site, Twenty Twenty theme is currently active on your site. Download the Travel Ultimate Pro that you have purchased and set active on your site

If you don’t have downloaded the theme yet
download from this link https://themepalace.com/my-account/

@WOODSMAN, you will get the code of the Event Section on the file path unveristy-hub >> templates-parts >> home >> news-and-events.php line no. 95, 96, 97

@MENYAK-TULKU, the CSS you wrote is incorrect. Here is the correct one

.site-description {
font-size: 25px;
}

It’s should work. Can you please share your site URL and if possible the dashboard login?
we will inspect and let you know

Don’t worry it’s just a warning it won’t create any issues on the site

Could you please send the screenshot of the warnings? We will inspect and clear warnings in a future update

Hello,

I have visited your site. The booking button is working well
as you can see the screen record
https://www.awesomescreenshot.com/video/15573130?key=ea2812c32daeb2e50339cdade9860fb8

I thought you had managed to fix the issue. As you have mentioned I am not logged in to your site and the booking button is working on my side

It’s strange how it is working on your side

could you please verify this on other devices? May be due to a cache it is not working on your browser

You can add this CSS in the Additional CSS.

here is the Code

.wp-block-section.header-media{
min-height: 1280px !important;
}

@media screen and (max-width: 1040px) {
.wp-block-section.header-media{
min-height: 510px !important;
}
}

@media screen and (max-width: 767px) {
.wp-block-section.header-media{
min-height: 510px !important;
}
}

@media screen and (max-width: 567px) {
.wp-block-section.header-media{
min-height: 360px !important;
}
}

You will find Additional CSS inside Appearance >> Customizer >> Additional CSS

Add the CODE there and published the site

It is necessary to have different image sizes because a single image size cannot be adjusted to display as a thumbnail, medium size, and large image. Three images are created by WordPress default option and others are generated by theme. we need to display different image sizes in different places that’s why it’s required and cannot be optional.

If you set WordPress created media sizes to 0, your future gallery display may not work properly. I don’t recommend you to do that as it may cause problems in the future.

If you want to do it anyway this article may help you
