Can't configure GZIP

Hello,
I have the trial version and run the free-scan. Following your advise I installed GZIP. Result from the scan is, among others, that I need some files compressed and optimize pictures. The red X remains after applying the fix. Reason is that I need to configure GZIP.......... when I want to do this I get the error "access denied" . I appriciate some advise :slight_smile: Kind regards, Rob
