Orange warning message after trying to install any plugin

I am unable to install any plugins. After attempting to any installation a strange orange unhelpful warning sign appears at the top of the page. It contains only one word, 'message'. Not sure what to do with this one. If it offered event the slightest clue it might be helpful. This only affects wpmu plugins.

    Hi Derek

    Hope you had a wonderful day.

    Can you turn on debug mode in WordPress? To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

    define('WP_DEBUG', true);

    In order to enable the error logging to a file on the server you need to add yet one more similar line:

    define( 'WP_DEBUG_LOG', true );

    In this case the errors will be saved to a debug.log log file inside the /wp-content/directory.

    Depending on whether you want your errors to be only logged or also displayed on the screen you should also have this line there, immediately after the line mentioned above:

    define( 'WP_DEBUG_DISPLAY', false );

    The wp-config.php is located in your WordPress root directory. It’s the same file where the database configuration settings are. You will have to access it by FTP or SFTP in order to edit it.

    Past errors here. If file is very long, please paste them to a text file and attach with your reply.

    Moreover, I could tell you better about the issue if I could see it live, check your current configuration and make some tests on your site. Would you mind allowing Support Access so we can have a closer look at this?

    To enable support access you can follow this guide here:
