Hello!
We’re sorry for the inconvenience issue.
We’re very so for the delay as well.
I understand the issue you’re facing and I aware that you cannot do anything with the host configuration.
This step must be passed or you wouldn’t get all the benefits provided by the PRO edition.
Could you please try to disable all the other plugins so you get some free memory for the Plugin to pass the installation process?
If you still unable to install the Plugin. Could you please provide us (through the private contact form or send mail to support@css-javascript-toolbox.com) WordPress access so we can try to get around.
Hope that helps.
Regards,
AHMeD
