Thank you for your answer, I have changed the plugin to Google translate and solved the problem, but I have another problem.
I am not able to change the template of the blog page. I am choosing any kind of template shown in the page attributes but it does not change. I want to use the grid template with or without a sidebar but it will not change. the only thing that changes is the container and container full.
Speaking about the page templates – one can choose to show and hide elements ( Service, Portfolio est) from the front page but is it possible to use the templates and change the images for an inner page for example -there is no use to show the user one and the same images and information on the home page and on some other inner pages as well.
I am not able to change the page header -to upload an image . Only the color is changeable. thank you for your answer
