Issue:

The customer is getting a WSOD with a black bar across the top when using BuddyBoss Theme with AWS. Other themes work fine. AWS mentioned that the customer contact us for help. 

Solution:

If the customer is experiencing a white screen of death (WSOD) issue, it usually indicates a PHP error. Ask the customer to check the PHP error logs on their AWS server. The logs may provide insights into the specific error causing the problem. The logs can usually be found in the /var/log directory or a directory specific to the web server (e.g., /var/log/apache2/error.log).
