The tags aren't working

The tags that are in the articles aren't working. When I click on them, I'm redirected to the error page.
My website: viagemdemoto.com

Hi

Can You please tell me exactly where this tabs are ? I cannot see them on Your site.

They are in all articles, like this: http://viagemdemoto.com/viagens-pelo-brasil/3713-viagem-de-pop-110-brasil

See the image where they are.

I think the URL is wrong: http://mysite.com/component/tags/tag/xxxxxxx
and doesn`t point to the page it should.

Hi

Och, You meant those tags. Sorry, was thinking about different thing. Please try rename /html/com_content/article/default.php to _default.php . This will test if problem is in joomla or in template override. If this test will show that links are working with file renamed send me an ftp to my mail [email protected] if it will be still broken, than You will need to report this to joomla developers.

I renamed the file and the problem continued. And I changed the template and it also has problem. Should be problem in Joomla.
I hid the tags until I solved the problem.
Tks

Hi

Yes, it looks like it's on joomla side, but there are extensions which can still affect that. Are You using any additional SEF extensions, for example sef404 ? If yes than try disable it and check.
