Thank you <LiveComposer>. Now it is working.
I don’t have idea why was broken. I have reinstaled the plugin 2 times, the theme, the wordpress, cleaned the cookies and finally start to work. Also I have contacted with the the author of the theme for support, but I solved the issue before his answer.
Maybe his advices can help others:
1.Probably it was an ISP or server connection issue. I tested your LC and it is saving properly. Please check the screencast attached to this email.
2.When you bought the SEO WP, the Live Composer was a premium plugin. From few days ago the plugin developer chose to remove it from market.
3.You cannot update the plugin in that way, because you didn’t purchase it :). We provide plugin updates once we finish to test them for compatibility with our theme. Please follow our updates and every plugin will be working fine.
