I want to add a logo on my WordPress website by customizing the theme "Bard", but every time I select an image from my library, it leads to a **blank** page. The same happens with the header image. And yes, I've tried changing the theme but am facing the same issue.

**EDIT**: Yes, the size of the uploaded file matches the criteria, and yes, I can upload images in the library, and in posts and pages too. Also, I'm using Hostinger, not local host.
