I’ve had some presets for my titles such as “Buy %post_title% from Sitename” after the 4.0 update the post title I defined in my individual posts was stripped out…? And only my post title / H1 was used instead in the post_title placeholder.
Before I had changed my site title to whatever I wanted and it would go into the post_title tag. I have thousands of pages so I cannot go through and re-update all my pages. When I revert to 3.0 the titles are back to normal. Is this a known issue?
