I updated to version 5.3.3.3, and everything looks great, except I am sill getting a “A PHP session was created by a session_start() function call. This interferes with REST API and loopback requests. The session should be closed by session_write_close() before making any HTTP requests.” Which seems to be a problem with Unyson, which I am using for mega menu and the header. If I turn off Unyson, my header and menu break.
My whole site looks fine with the new update, but if I try to deactivate unyson, the menu and heading do not display properly, despite my settings in the theme. The side navigation becomes all text at the top, and my logo becomes the jevelin logo.
