Looks like the “`db_shared_buffers`” on line **37** needs to be properly indented (it needs to have 2 spaces before). ---

Can you paste the actual text content of the file rather to posting screenshots? ---

For reals. Sanitize your data before sending it @M_c_Tau . Attaching it to the post was the wrong move. Just do what @Tom_Newsom said and paste it as a code block (and sanitize your user creds)… I would suggest changing your passwords as well as deleting your attachment post. Your password is clear as day! ---

That’s a random password. However, I removed it already. Thank you for your advise. @zogstrip it works like charm! Many thanks ---
