Hello! My site is running Moodle 3.6.2+ I recently loaded office 365 plugins and now when I go to Site administration > Notification (/moodle/admin/index.php?cache=1) I get the error "Exception - Class 'object' not found". The browser shows up with this error "Failed to load resource: the server responded with a status of /moodle/admin/index.php?cache=1 503 ()". 

I turned on debugging and got the following errors. 

Debug info:

Did you update PHP as well? That's an error caused by a new reserved word in PHP 7.2.

The maximum version of PHP for 3.6.2 is PHP 7.0. If you want to use PHP 7.1, 7.2 or 7.2 (not newer) you need to upgrade to the lates version of 3.6 (3.6.10)

However, Moodle 3.6 is now completely unsupported and you should consider upgrading to a supported version.

No. PHP has not been updated. We are currently using PHP 7.2.7 but we do have plans to upgrade our Moodle environment to 3.8. Thanks for the information. smile

Related to what Howard has already suggested ... upgrading Moodle ... (which is a good idea), the essential theme seen in debug output also means you'll be seeking another theme:

https://moodle.org/plugins/theme_essential
Please note: Essential has reached 'End of life' at Moodle 3.6 - last version for.

So before you upgrade from 3.6 to higher version of Moodle change theme to one that came stock with 3.6 - more, clean, or boost to make that upgrade easier. Can do that just prior to upgrade easily via config.php file:

$CFG->theme='boost';

I mention cause been there ... done that! ;)

Might also check any other add on you have installed to assure it has a compatible version for destination Moodle version.

Thanks for this tip, I wasn't aware of this since I'm still a Moodle newbie.

I finally upgraded to 3.8 and followed the suggested step (via config.php file: $CFG->theme='boost'; prior to the upgrade. ) But I'm still getting the same errors.
