Installation problems WP Smush Pro

I just purchased the pro version of WP Smush but I am unable to install it. I installed the Dashboard but when I tried to install WP Smush Pro I got a 500 error and WPMU DEV Dashboard can't find my website.

    Hello there Regan,
    I hope you're having a great day and thanks for reaching us!

    Did you install the free Wp Smush version before trying the Pro? Please make sure you remove the /wp-smushit folder in your /wp-content/plugins folder via FTP first. Then go ahead and try to instal the WP Smush Pro again.

    You can also try raising your memory limit 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.

    Could you then:
    1) Clear all the caches on site (and on server if there are any)
    2) Clear your browser cache
    3) Login to the site again
    4) Try to install the plugin

    If the above doesn't work can you please grant support access from the dashboard plugin so we can take a closer look?
    This could be done via Dashboard - WPMU DEV -> Support -> Support Access -> Grant Access or by following this guide here:

    Looking forward to hearing from you!

    Warm regards,
