Hi,
yes I have, so this could be it - thank you, I was thinking that something was broken on my site.
Maybe you should think of putting some notification under Minify settings, if CloudFlare is enable to grey it out, or to say that it can not be enable due to minification already on somewhere else (i.e. CloudFlare), could have helped me not to pull out my hair why it is not saving settings ;)
Thanks,
D.
