Unable to make changes, one page has different font


I have three separate issues on my web site: www.prirodnacistickavzduchu.sk

I am unable to make changes to some of the pages on others I can make one change and can not make other. I tried to deactivate 3rd party plugins did not help.

On page cennik the whole page has different font.

I have FB share plugin, when sharing different pages different picture is shown

Previously I tried to install FB like box plugin from facebook and the installation crashed and had to upload the whole site from back up. until then all worked perfectly with all the installed plugins I have now.

Thanks for help
