I created a multilingual web site(blog) and everything worked fine, except filtering by tag.
My web site is on Joomla 3.4.3 and I am storing content using K2 ver. 2.6.9.
My articles have tags and when I tap on tag (filter articles by tag) I'm getting a 404 error page. Filtering by tag crashes when I use SEF, if I turn off SEF - everything works properly. Any ideas how to solve the problem? What could be the source of the problem: Joomla or K2 or maybe the template?
Problem is the same on Joomla 3.4.4 (I have local copy of the web site). I tried to switch off web pages suffix but it didn't solve the problem.
I don't use 3rd party applications for SEF and content. SEF is core Joomla option. Also there are advanced SEF options in K2. Joomla and K2 forums haven't helped to fix issue.
P.S: turn off SEF is not a solution.
