I have a site that I am working on to replace the current production site. I have moved all my data and when I attempt to load the RSS feeds for the categories in K2 it returns a 404 error.

My host looked into the error and found that when the RSS feed is loaded it returns the following error in php.

[11-Dec-2019 18:43:35 UTC] PHP Warning: count(): Parameter must be an array or an object that implements Countable in .../templates/ts_newslinen/html/com_k2/templates/default/item.php on line 314

[11-Dec-2019 18:45:15 UTC] PHP Warning: count(): Parameter must be an array or an object that implements Countable in .../templates/ts_newslinen/html/com_k2/templates/default/item.php on line 314

That line in the item.php is as follows.

"<?php if($this->item->params->get('itemExtraFields') && count($this->item->extra_fields)): ?>"

I have error reporting set at maximum but not seeing any errors returned. You can see the page that is returning the error on the RSS feed by going to bit.ly/2qO1Bk4

On the production site in which I cloned the development site from RSS feeds work without issue. The only difference between the two sites is an updated template that I installed that will allow me to move to a newer version of php.

Current info on the site:

Joomla - 3.9.13
K2 - 2.10.1
PHP - 7.2

Thanks for the help.

Updating K2 to v2.10.3 dev release fixed the issue.

Thanks for the help.

Ha. Yes correct on that. I will make the edit to the post for the next person who might find this.
