Now for a specific block, I wanted it to be visible only on the front page. So I edited the block visibility settings for specific pages and made it <front>.
But the block is showing up in all the page. I have also tried other options like roles. In all the cases the desired result is not realized and I keep getting the blocks visible in all the pages for all the roles.
A background of situation: I had a theme, using which I have developed a sub-theme. Has anybody encountered something similar?
