HI,
Website link is http://jobsbarcelona.es/
Now i did check some of the forums but i am not still able to fix it.
My site theme is Thesis? I also updated the theme and my wordpress is also upto date already. I also checked the webmaster tools to check if site is hacked or not, but that's also is perfectly fine.
I did tried to disable some wp security plugins and all plugins but it still shows the same error. I am not able to remove the error still. Can you give me some suggestion by which i can remove it.
