Update to 3.7.0 failed

An error occurred

Class ‘Monolog\Logger’ not found

I did the manual update.
Has somebody an idea wat to do?

Hi,

It sounds like some important files are missing. (Maybe the update came to an timeout and was interrupted)

Reuploading all files should fix the issue (pay attention to keep the config/config.ini.php)

You can find more details here:

Thanks. I wil try it.
