@janisi Please tell us what solved your problem.
I think I found the problem. When I deactivate all plugins and refresh the site, it seems to work. The problem does not occur when I enable all plugins exept for WordPress SEO. Does this solve it for you?
I’m having the same issue. I’m also using WPML, but this doesn’t seem to be the problem, because diableing does not solve the problem. I’ve also disabled other plugins and tried renaming my home.php template. Nothing seems to work.
Has anybody else encoutered this and have a solution?
