White screen when not logged in

Hello, I use the “Houzez” theme by Favtheme which uses Framework Redux. I have a problem with a blank page when the user is connected (a user not logged in). On the other hand, when I’m logged in, all the pages are activated correctly (Except those whose content is managed exclusively by the FR module).

I’ve tested the plug-ins and it seems that white pages no longer appear when the Framework Redux module is deactivated.

In debug mode, i only have this :

According to my tests, the problem is clearly with the Framework Redux plug-in.

Are you aware of this bug?

I can’t simply deactivate the module, as it is essential for displaying the theme correctly.
