Snippet and authorization broken MODX Rev?

Question

PHP

Today, getting started, I found that some of the snippets do not work.
During the analysis, I found that this code does not work:

$holder = $modx->getObject('modResource',array('alias' => $_GET['href']));
echo $holder->get('pagetitle').'|TIDmuS|'.$holder->get('content');

Fatal error: Call to a member function get() on a non-object in /home/lol/data/www/muscat62.ru/core/cache/includes/elements/modsnippet/2.include.cache.php on line 22
Previously, this code worked - it received page data from ModX.
When I try to login, it says: Account not found. Check the username and re-enter the password for a new attempt.
There is an entry in the database. I also changed the password following the instructions (erase the salt and reset to password). But unsuccessfully.
I tried to change the database user - no change.
Also, another admin on VDS tried to install owncloud. As a result, it doesn’t go further than the database settings - error 500. Maybe it's in the database.
At the same time, the rest of the scripts work fine with the database.

Modx needs to be restored.

Show var_dump($_GET) when requested.
I suspect that you have a CNC. Replace $_GET['href'] with $_SERVER['REQUEST_URI']
