I installed XOOPS 2.2.3 for another site.
Installed ok. I login to admin, and screen is blank. I have gone to recovery.php and selected debug mode, and still nothing. I can log into recovery mode, then go back to home page and I am logged in as admin. I then go to admin panel to try to set debug. Log out, try to log back in, but still nothing.

The only errors I can see are this in recovery.php:

Notice [PHP]: Undefined index: session_expire in file recovery.php line 77
Warning [PHP]: constant(): Couldn't find constant _MI_DEBUG_MODE in file recovery.php line 89

Any advice?
