Fatal error when trying to activate Clean Talk plugin

Hello, I’ve added this plugin to all my wordpress sites and it is working wonderfully and I’m very grateful for that.

On one of the sites it is experiencing errors. This is the sequence of events, and I hope you can help because I really want to use this plugin:

Installed on Nowwrite.net which in my GoDaddy hosting is the top level site: all the other sites have their own folders and Nowwrite.net does not – folders and files are outside of those.

When I first installed the plug in and scanned the site for malware a few days ago, it showed all several thousands of the other files from my other sites as “unknown” – I guess because they are inside the top level Now Write folder. But I was able to deal with a few other suspicious files.

Two days later the site went blank and I couldn’t get to login.

I deactivated the plugin folder, went back in WP and reactivated the plugins one at a time. Clean Talk showed a line about why it was overloaded and a fatal error. I don’t have the exact code. I tried deleting, installing, and activating again and this time it just said, “Fatal Error.”

On advice in this forum, I deleted the plugin again, downloaded from your site, made a zip and uploaded directly. Again when I tried to activate it said, “Fatal Error.”

Please advise.
