Question

Developer asked me for the following:

Please allow the read and write permission  to  theme folder for access.
/bitnami/wordpress/wp-content/themes/Divi/archive-hall_of_fames.php: open for write: permission denied

How do I change this via the command line?

Answer

Hello.

Is it possible to connect to Lightsail with SSH?  
Please check the following document for information on how to connect to Lightsail with SSH.

Once the connection is established, try running the following command.  
You can grant read permission to the file "archive-hall_of_fames.php" by executing the following command.  
If you do not have enough privileges, you can give them privileges by changing the number in the "775" part.
