I cleared cashe, deactivated all plug-ins but that not helped. By the looks of it I need to re-upload the zip file using the FTP which I never done before. I’m just afraid of making things even worse if I try…
They also suggest to change the theme to twentytwelve and see if that helps, but I don’t want to change the look of my site.
Does anybody know if WP are releasing the fix which will sort the things out?
Or else, what else can be done without using the FTP?
