As you can see in the screenshot, when I click on a Blog, the title/header of the blog is no longer showing... although I have Blog Title set to Show. Help please!
Please always attach a link to your website so we can check it out. If the page is offline(localhost), then our help will be limited. You will have to contact us when the page is online. Also, please make sure that the page is not under maintenance before you provide us the link.
Your title color is white, that is why it is not visible.
Please, go to Betheme -> Theme options -> Colors -> Headings, and change the H1 color to anything except white.
