Multiple Errors after Upgrading to 5.2.7

Hello,

I just upgraded from 5.0.x to EasyBlog 5.2.7 and multiple features are not working properly, including:

- Images are now missing from the 3 posts in Featured Slider - see https://www.itcareerfinder.com/brain-food/blog.html
- Cannot remove “IT Career Juice Blog” from header of all pages (blog view & entry view) - see att. screenshot
- Cannot remove "Featured" text and star mage from featured posts in entry view - see att. screenshot
- Also, many of the backend settings I change do not properly affect with front-end. What's the disconnect?

Please advise on these fixes ASAP.

Thanks,
Daniel
