Dear all,
I'm new with this plugin.
I tried to integrate it into my site using the suggested syntax {YouTube}_nAz4e-MQE4{/YouTube}
on this page:

claudiaghiraldello.it/mostre-centro-culturale-cerrione-2022/2-contenuti/126-centro-culturale-avogadro-2022

but the space where the video should be visible is blank. It seems a plugin loading problem.
PHP 5.4.4-14+deb7u2 + Joomla! 3.10.1 Stable
Any suggest?

Thank you all
