Out of 3 websites hosted through AWS Lightsail, one is showing http error 500 due to allowed memory size exhausted. Is this a temporary problem. Do I need to upgrade my AWS Lightsail hosting? Is it possible to address this issue by increasing memory size in PHP settings?
 
Yes, increasing memory_limit in PHP Settings on domain level will help.

However, make sure there is no .user.ini or .htaccess that will override that.
