Hi.
Is there a limit of items for each category? (I use joomla 1.5 e k2 2.4.1)
No problem to place the article in the category but in frontend whene I click "read more" i see a blank page for all items in that category. If I unpublish an article in that category I see it normally.

What is the problem?
Help me, please

If you are getting a blank page, turn on joomla error reporting and see if there is an error displayed
I havent seen a published limit on records in the tables, (there may be one, but it will be limited by your sql install and server storage, probably not k2 or joomla

What else have you added to your site that may be causing things to act funny at this point
