Hi
www.versionedemo.eu/blog/index.php
If you click on emoticons menu on the right position the articles that are filtered by this k2 tag menu shows the code and not the video.
Also the date of the article is wrong because the month is SP_APRILE instead of simply APRILE.

Thank you very much for your help

The Language strings is a template issue, which should be addressed by the template's developer.

The {youtube} tags are wrong, if you look at them they contain HTML tags which should be stripped.

Finally [sp video] is from an extension which is not affiliated with us. You should address this issue to the devs of the extension, since tag listings support content plugins.

I supposed it was like you're saying but Joomshaper support told me i have to ask to this support forum. I'm really confused and feeling like having no chance to solve this issue.

Hello
[sp video] was not developed by us, so I do not know anything about this extension.

The language strings are specific to your template, www.versionedemo.eu/blog/index.php?template=protostar (dates are functioning normally) so again this is a 3rd party issue.

The extension which is ours -> AllVideos I told you what is wrong with the shortcode you are using.

I am sorry but I cannot provide support for products that were not developed by us.

Thank you very much for your answer Krikor. I perfectly understand your point.
I simply made a mistake choosing the company where i bought the template.

I am sorry to hear this David.
I hope that you solve this issue. Feel free to c/p our conversation for your use in other forums.
