I'm running Gantry v4.0.6 on a WordPress 3.6 installation.
I've been setting up a default layout using Gantry, and this works fine. However, when I select the "Front Page" override from the dropdown in the Gantry control panel, Gantry... breaks.
The Gantry control panel loads without any CSS or styling, so everything's all on one page, as you can see in this image. At the bottom of the page, I get this error:
Fatal error: Out of memory (allocated 65798144) (tried to allocate 33890 bytes) in /home/[...]/wp-content/plugins/gantry/admin/index.php on line 300
This is frustrating and impeding my ability to build this site. How can I fix it?
