WP Smush Pro will not install

When trying to install WP Smush Pro it gives an error "Server error status: Internal Server Error [500]" that said I have already increased all limits, removed the free version, and still get the error.

I have looked through other support cases and others seem to have the problem but there is no clean solution anywhere just a lot of "try this" with no luck. A zip file of the plugin would be nice to just manually install then the issue would be solved I assume.

    Hey Brandon!

    Hope you are well!

    I see that you are using WordPress old version (4.5.11) but current version is (4.9).
    Using Old version of WordPress is harmful for your website.

    Here is a article about why you should use the latest version of WordPress. Also you will learn more how to update WordPress. here is the link: https://premium.wpmudev.org/blog/update-wordpress/

    I highly recommand you to update the WordPress first, then try to install our plugin again, becasue of this cloud be the reason of causing 500 error.

    Note that: Before updating the WordPress you must create a backup of your website & save it to your local computer/dropbox/Google drive. So there are no change to lose it.

    After all of these if you still see this error, please send me the debug log, here are the steps to how to enable the debug log and get it:

    Enable Debug Log
    from wp-config.php file (located in root WP folder), replace the define('WP_DEBUG', false); with this below code:

    // Enable WP_DEBUG mode
    define('WP_DEBUG', true);
    // Enable Debug logging to the /wp-content/debug.log file
    define('WP_DEBUG_LOG', true);
    // Disable display of errors and warnings
    define('WP_DEBUG_DISPLAY', false);
    @ini_set( 'display_errors', 0 );

    > Try to upload the plugin.
    > When you see 500 error, grab the debug.log from inside the wp-content directory.
    > change debug.log to debug.txt file.
    > Upload debug.txt file to any fileshare service like dropbox or google drive & share the link to me.
