GTranslate

I have GTranslate - which uses Google Translate - to translate the content on my website but when a different language is selected I get a ‘Bot Protection Firewall. Blocked because of Malicious Activities’ error !!!
I flagged this with GTranslate and they said I need to white list their IP Addresses.
Which is quite a long list…
I’m confused ??
How do I do that ?

I also need assistance on this same issue. I’ve set their IP Addresses to “Allow” on my firewall rule but that didn’t work. I also went to “Tools > IP Access Rules” but I can only input IP ranges of /16 or /24 but I need to add ranges of /29 and /28
