What's going wrong
Site owners using the Block Manager plugin report that its settings screen goes blank, shows only categories, or stops listing blocks altogether. Reports follow WordPress core updates and conflicts with the Gutenberg standalone plugin, GiveWP, Gutenverse, and Jetpack. Some users see a build error or console errors that hide the Blocks and Categories tabs. Because the block list is the core of the tool, these sites cannot change what editors see until the screen loads again. The pattern points to a need for compatibility testing across common plugin and theme combinations, and for a clear way to confirm the screen works after each update before it reaches live sites.
