Hide title page

Guys, I’ve seen the previous post on this topic and when I go to global settings and choose to hide the title page with: .entry-title {
display: none;
or by going to Tools > Edit Global Settings > Default Page Heading and set Show to No.

The title page still appears. I am using WP theme Velux.

Any help is appreciated. Thanks!

I am having the same issues with my site. I have done all the troubleshooting that has been advised and titles are still there.

.title {
display: none;}

.page-title-container .page-header .page-title {
display: none;
