Fatal Error in Garden\EventManager.getHandlers();

in Vanilla 3.x Help

Hi,

I attempted an upgrade from 3.0.2 to 3.3 today, got as far as step 7 of the upgrade article (https://success.vanillaforums.com/kb/articles/158-upgrading) however when trying to run the DB updates, I noticed that I'm getting a 500 error.

My initial installation was 3.0.2 with an archive upload and unzip, I attempted the upgrade by directly overwriting files (apart from the ones suggested to delete) with the files from 3.3 zip via SFTP.

From the error message in debug mode, I gather the upgrade wasn't successful to 3.3 either as I still see the old version. I attempted to correct that in the conf/config.php but the debug error still shows 3.0.2.

I do have a safety backup of the old installation, but we're hoping to get it up to date.

Any help is appreciated and thanks in advance for your time :)

Below is the error report:

Call to a member function get() on null

The error occurred on or near: /var/www/webroot/ROOT/library/Garden/EventManager.php
