Hummingbird installation error

I have seen this error in other tickets but have found no resolution (one suggestion for another user was to update the PHP version, but I checked and have 5.4 on my hosting, which was within the responders recommended versions).
When I try to add the Hummingbird plugin, I am receiving a red error bar that simply says "message" (see attached screen shot). Thanks in advance for your help.

    Hi elijah, hope you had a wonderful day.

    Can you try manually installing the plugin? Download the plugin from HERE and uncompress the file on your computer. Now login to your server with any FTP Program and upload the uncompressed folder on your computer to "/wp-content/plugins/" folder on your server. Then try to activate the plugin from "Dashboard > Plugins" section. You can get more idea about installing plugin through FTP from here: https://premium.wpmudev.org/manuals/wpmu-manual-2/installing-regular-plugins-on-wpmu/#ftp

    If it fails to activate, it will show error message. Can you forward us that? Can you also turn on debug mode in WordPress while trying to activate the plugin? To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

    define('WP_DEBUG', true);

    In order to enable the error logging to a file on the server you need to add yet one more similar line:

    define( 'WP_DEBUG_LOG', true );

    In this case the errors will be saved to a debug.log log file inside the /wp-content/directory.

    Depending on whether you want your errors to be only logged or also displayed on the screen you should also have this line there, immediately after the line mentioned above:

    define( 'WP_DEBUG_DISPLAY', false );

    The wp-config.php is located in your WordPress root directory. It’s the same file where the database configuration settings are. You will have to access it by FTP or SFTP in order to edit it.

    Past errors here. If file is very long, paste them to a text file and attach with your reply.

    Have a nice day. Cheers!

    Hi elijah, hope you had a wonderful day.

    I checked and have 5.4 on my hosting, which was within the responders recommended versions

    I totally skipped this fact as you confirmed you have PHP 5.4 but I just logged in with Support Access and found, your server is running PHP 5.2.17. Please check the attached screenshot for reference.

    Please talk to your host regarding this and I believe, upgrading PHP version will solve the issue for you.

    Have a nice day. Cheers!
