I have installed k2 2.0.0 ( 20th june) on two sites.

I cant delete category on site. Then i delete category for test on another site ( and another server) - i cant see categories listning -
Warning: Invalid argument supplied for foreach() in /mountedstorage/homexxx/xxx/xx/mysite.ru/administrator/components/com_k2/models/categories.php on line 121

Then i relogin in admin panel- i see categories, but if try to delete- problem return

Hi. What error are you getting when you try to delete a category? Please provide some more info

Hi,
I have the same problem. Error messages are turned off at my server, but I am not able to delete categories. (with same version of K2 and Joomla 1.5.11/12)

Please be more specific on what happens when you try to delete a category. Turn on error reporting and post the error that you are getting.
