Hi All,
I have a strange issue I cant seem to solve now for a few days.

1. I use K2 v2.9.0
2. Joomla 3.9.4
3. PHP 7.0.33
4. K2 v 2.9.0
5, Template - JA_simpli

Issue : I spend time in my JCE Editor, writing an item in K2, with paragraphs, bold titles, spacing , hyperlinks etc.
Then I publish it. But when I look at the articles on the website, it has NO formatting at all, hyperlinks are also missing or not working. Its one big continous block of writing (as if I wrote it in notepad). I go back into the editor and it looks perfect !? (Heading, Paragapgh , formatting etc)

I have swapped templates and still have the same issue. I have enabled ALL my plugins and disabled them and still the same issue.

If I publish the Joomla (standard) article, then it looks fine with all the formatting - but I want to use K2. ????

Anyone have any ideas ???

Really appreciate the reply. I must admit that Im a little confused about "related filters enabled in the K2 Settings (backend)" , like where in the backend , what filters ??? But I will have a look at the Options for Items and Options in Category and see if I can see anything.

If you have any further detail, specifics, then it will help alot :) Thanks again

Well I found it !!!! Thanks for the advice.
Yes it was in the following area:

K2 Categories -> Parameters
Then under the Content Tab - goto Content Cleanup Section
Introtext HTML cleanup (tag strip) - Was set to "YES" - I turned this to "NO" and my issue was resolved !!!
Would not have been about to do this without advise. Cheers :)
