Hi+
Thank you for the super quick response and helpful hints. I do have other backup and security plugins on this site. Would those be potentially causing an issue with this one being installed?
Thanks!
A security plugin with a WAF firewall could cause this problem. Temporarily turn off the firewall and see if that works.

Oh! I will give that a try first. Thank you!
Corrupt browser cache can cause this problem too. Try clearing your Browser cache and plugin cache if you are using a caching plugin. If you are using Cloudflare then clear your Cloudflare cache.

Okay, thank you for all of the helpful hints. I will give it a go over the next few days and update here afterwards.

Hi+
I cleared the cache and temporarily turned off the firewall then it was able to install & activate. I turned the firewall back on and was able to still set up this plugin as needed.
Thank you very much for the guidance!
