Hi Nebojsa,
1. It’s only happening for your AUSBILDUNG content.
2. In this issue, the WPML support team can assist you.
3. In this issue, you could read this article https://www.sparringmind.com/speed-up-wordpress/
4. It’s may possible to show the image to write some custom CSS.
5. Use the CSS below to get every second word not bold
.split--words span:nth-child(2n) {
font-weight: normal !important;
}
6. Based on the UX, if you hide the scrolling option then the users who are using small screen devices, they will not see all of your website menus.
Best Regards,
ThemeLooks Support Team
