500 Internal Server Error When Trying to Install WP Smush Pro

Hello, I am trying to activate the WP Smush Pro plugin and get a red/orange bar at the top that says "Server error status: Internal Server Error [500]". Please advise on how to get this to work on my site. Thank you.

    Hello Lindsey,

    I hope you're well today and thank you for your question!

    Usually the "500 Internal Server error" in case of WordPress is caused by insufficient memory limit. I accessed your site and I can see that it's set to 40M only which is actually a very small amount.

    Please start with raising that by adding following line to the "wp-config.php" file:


    Make sure that this line is located above the "/* That's all, stop editing... */" line and then:
    - clear all the caches on site (and on server if there are any)
    - clear your browser cache
    - login to the site again
    - try to install the plugin

    If that doesn't help, let me know please and I'll further investigate it.

    Kind regards,
