Hello Keith,
Thanks for writing in!
I tried looking at the licence manager, however as you have multiple licenses it’s a bit difficult for me to figure out the website that’s having issue. Can you please share the admin login details in secure note so that I can take a closer look?

In the meantime please try out following solutions:
- It’s mentioned that you are using Pro theme. Please make sure that you are using latest version of Pro Theme 2.5.5. You can take a look at following resource to update. https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62
- Increase the PHP Memory Limit of your server. Click here for more detailed information and how to increase the PHP memory limit.
If you still have problems kindly get back to us with the result of the steps above and URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case.
Thank you.
