Error Message on Website

Hi,

I got this message on our clients website, I have no idea what to do? Will someone please assist me with this.

An error occurred while executing this script!

1. If you are a Contao user, contact the administrator of your website.
2. Open file system/logs/error.log and search for a corresponding entry.
3. Open file system/config/localconfig.php and add the following line:
$GLOBALS['TL_CONFIG']['displayErrors'] = true;

Read the Contao FAQs or visit the Contao support page.

To customize this notice, create a custom template file named templates/be_error.html5.

Thank you

Actually, the error message tells you how to get more information! You can add the PHP line to the file (3.). But if the backend still functions please check the log, to see if there is any error logged. Finally, also check (via FTP /system/messages/error.log) it should contain error messages regardless of 3..

Then post the errors you find here, if you do not know how to solve them.
