Hi,

I have a blog web site on Joomla 3.4.3. I am using K2 for storing content. My articles have tags and when I tap on tag (filter articles by tag) I am sending on 404 error page. Filtering by tag crashes when I use SEF, if I turn off SEF - everything works properly. Have any ideas how to solve the problem? What is the source of the problem: Joomla or K2 or may be template?

Here is my blog and example of 404 page iman007.com/en/tag/Android.html (SEF is turned on)
If SEF is off then my filter by tag "Android" looks like this: iman007.com/index.php?option=com_k2&view=itemlist&task=tag&tag=Android&Itemid=101&lang=en

Problem is the same on Joomla 3.4.4, K2 is 2.6.9.

P.S: turn off SEF is not a solution.

Thank you.

Hello,

I can see the issue here as well: iman007.com/en/blog/7-it/social-music-service.html

Are you using K2's advanced SEF or a 3rd party sef extension?

I am using Joomla SEF (general options) and K2 SEF advanced options. I don't use 3rd party sef extensions.
I have solved problem with this url iman007.com/en/blog/7-it/social-music-service.html - I have added ID number to the url articles.
Problem with tags haven't solved yet.
Thank you for notification on the problem web page.

Can you remove the .html suffix and try again please?
The id part is crucial if you have items with the same alias.

I have this web site on my local PC and just have tried to remove suffix (In general options -> suffix switcher) but it hasn't solved the issue.

Can you send me a screenshot of your Advanced SEF settings?

Here is url of advanced setting Advanced settings
Here us url of tags settings Tags settings

It is settings from the web version, not from local one.

I tried to change SEF settings, but it didn't help.

Could you change the /tag/ prefix to something like eg: content just to test it?
Furthermore can you test with the dev version in your localhost?
You can get it from here: getk2.org/assets/get/

I tried to change prefix and tried dev version of K2, but it didn't help.
Also I tried to turn off language filter (as my web site is multilingual) and in this case tag filtering worked, but it is not a solution as in such case my web site will not be multilingual. But it helps to get that the problem is in language filter. When lang filter is on url looks like this:When lang filter is off url looks like this:

Thank you for reporting this Andrew, we will look into this and let you know.
