This may sound stupid but I noticed that sometimes I have to scroll down to see the save button. Good Luck!
I got on the site two days ago but now I can’t. This is extremely frustrating as I need the basic info. to make the plugin work.
I had Simple Captcha on my blog. When I automatically updated it, it said it was successful but when I went back to the plugins page, it had disappeared. I came here and downloaded the new version. I erased the old version on my blog and uploaded the new one into my plugins. Once I activated it, it worked.
