Hello Geri,
I am sorry about the issue you are experiencing with activating the W3 Total Cache Pro.
Can you please drop us a note directly via the support channel in Performance>Support and provide the details of your purchase so I can find your subscription?
If the license is showing and you are still not seeing the Pro version active, remove the license key from Performance>General settings, Licensing sub-box, license field and save all settings. Re-enter the license, verify the license with the “verify license button” and save all settings.
W3 Total Cache Pro should be active after these steps!
Thanks!
