Hello,

I have problem. The plugin is workong only under 1 post:
https://szabadnakszulettek.hu/ettol-leesik-az-allad-a-kutya-elkezd-futni-a-tigris-fele-de-olyan-tortenik-amire-nem-szamit-senki/
Anywhere else (https://szabadnakszulettek.hu) I can not see it. I tried to modify things, stopped other plugins but still not working. Do you have idea?

Thanks
