In system settings there are errors: modx?

Morning came and everything was OK, but after a while when you log in to the admin panel you receive the error notification, and any action you on. Tried to rename .htaccess did not help. How to solve this problem?

This error the directory kernel in open access does not affect anything you can't do it.
Put controlErrorLog and then the top right you will have a button by clicking on which you read your error. Either turn on the error log on hosting and read.

Either a local server you have something not configured until the end, or hosting something with the server.

The cache is initially clean - folder /core/cache - delete all. Or to put CacheClear and appears page . Click view cache will be cleared.
To install the app package -> installer in the top menu of the admin, there enter the name of the package.
For detailed instructions projectsite or googled to deliver the package modx revo - lola commented on June 3rd 19 at 19:04

Hello, you can easily - rename the file core/docs/changelog.txt in for example, old_changelog.txt
But first in the folder core/ hta.ccess is to rename, just. In General it is a glitch of the server.
