I have a template file for a site's home page which is named front-page.php that has several content blocks in it. I am seeing an issue where sporadically the edit areas for the blocks do not appear on the edit page form for the page. The content areas always display when you view the page, they just are not available to edit.
I have tried setting the template for the page to explicitly be the front page template, or setting the template to the default page. In either case the page displays properly, but sometimes it is editable and sometime it is not.
I just updated to the latest version of MCB but that did not make a difference.
Has anyone seen this happen, and have an idea what may be going on (a memory issue, interaction with other plugin, an MCB bug?)
