Can't login to manager modx revo?

Question

MODX

Hello. Does not enter the MODX REVOLUTION admin panel, just a blank white page and that's it. The error is written like this. How to deal with it?

/var/www/htdocs/core/model/modx/modmanagerresponse.class.php : 190) PHP warning: Parameter 1 to modManagerController::getInstance() expected to be a reference, value given

Answer 1

In the file core/model/modxmodmanagerresponse.class.php on line 190 (or close), there is a line:
$this->modx->controller = call_user_func_array(array($c,$getInstanceMethod),array($this->modx, $className,$this->action));
It should be replaced with the line:
$this->modx->controller = call_user_func_array(array($c,$getInstanceMethod),array(&$this->modx,$className,$this->action));

Answer 2

Hello, perhaps the problem is in the MODX Security Channel widget, it needs to be disabled in the system settings. Follow the link like: site.ru/manager/?a=system/settings and turn it off, see clip2net.com/s/3twsnDT
