I see that submission works on your page without problems but with latest K version I still get 403 page ,

index.php?option=com_k2&view=item&layout=itemform&task=add

user group permissions are set to be able to submit items,

can you please advise how to fix this or please advise how to get the category preselected in versions prior to 2.5

I am new to K2. Im have the same problem. Its a shame this is not working. I would have thought this was one of the key features of K2 to allow users to add and look after their own content. Has this feature ever existed or worked with K2. If so where can I download a version of K2 where this feature works. This feature is vital for an urgent project. Or is there a 3rd party component that can make this work. Thanks Al.

Check file "component.php" in your template
/templates/your_template/component.php

Hi. Please check that you have also front-editing enabled both in K2 user group permissions and K2 global parameters.
