Can't Activate FreePBX 13

Hey all:

A while back I upgraded to FreePBX 13 via the GUI, and everything’s been running good so far. I went to go activate my box today so I can install System Admin, but whenever I click on Activate, it displays a red Error message in the top right and loops back to the page asking if I want to activate. I ran fmportal debug, and I get this message whenever I click on the button:

[WARNING] (libraries/modulefunctions.legacy.php:7) - Depr eciated Function module_getinfo detected in /var/www/html/admin/libraries/featur ecodes.functions.php on line 42

Any idea what’s causing this?
