I enabled the tags at: oraiokastrotora.gr/ipopsifioi-simvouloi/dimotikoi/eklogiki-perifereia-oraiokastrou?ergt

And it seemed to work fine.
The links inside the modal are not working because it is an iframe.
If links were to be enabled then the content would be parsed inside the modal itself and not the parent.

Finally if you want to enable the same module at the under_component position you might need to remove the CSS animations.
You need to comment this line in your css file.
.cssanimations .seq-animation, .cssanimations .random-animation { opacity: 0; }

Tags working there because it is >=6 (items), try to enable it to oraiokastrotora.gr/ipopsifioi-simvouloi/topikoi/dimotiki-koinotita-pentalofou

yes it is a frame and as you say i cannot embed share buttons into modal right?

It seems you locked the administrator area.
I will need these credentials as well.

unlocked

A temporary fix has been provided.
It was an incompatibility with your PHP version.

I will provide a detailed explanation and a temp fix tomorrow.

As for the social buttons I think you can have social buttons.
Since the iframe content is a K2 item, all you need to do is enable the social sharing buttons from its category's settings.
