Hello,
So, I did some looking around, as I ran into this problem as well. Initially I just disabled the other .rss feed I was using, and the problem went away. Unfortunately, I also wanted to use mod_twitterfeed which caused the issue to come back. After some trawling google, this is the solution I came up with.
In helper.php (line 28 for me)
Change
// Includes
require_once(dirname(__FILE__).DS.'includes'.DS.'simplepie'.DS.'simplepie.inc');
to
// Includes
if(!class_exists('SimplePie')){ require_once(dirname(__FILE__).DS.'includes'.DS.'simplepie'.DS.'simplepie.inc');
}
With me? Okay, that caused this error:
Fatal error: Call to undefined method SimplePie::set_item_limit() in xxxxxx/modules/mod_jw_srfr/helper.php on line 45
So I went back into help.php, and commented out line 45
$sourceFeed->set_item_limit(intval($perFeedItems));
which got everything working. I fear it means I've now lost the ability to limit the number of posts, but I'll keep working on that to see what I can do.
Hope this helps anybody else in this predicament, and possibly might give the devs some inspiration to add these fixes to future releases. I know you guys get paid nothing to make this module; thanks for all the work you do on it.
