Compatibility issue with Post of the Day Plugin

[Duncan]

Hi
I have an issue with the mini calendar widget. It seems to have a compatibility issue with another plugin on the site (Post of the Day http://wordpress.org/extend/plugins/post-of-the-day/) when this is activated, I get an error when you use the previous/next arrows above the calendar. the Post of the Day plugin is pretty simple. Any suggestions what the issue may be?

Hi Duncan – what’s the error? I did visit the URL you provided when you opened this thread but I was unable to see the problem.

Hi
I have found a workaround by using an alternative to the Post of the Day plugin, but would like to find a fix if possible.

The error was:
Fatal error: Call to undefined method stdClass::is_single() in /home/sites/whatsoninglossop.co.uk/public_html/wp-includes/query.php on line 607

OK. I installed it and set up the [potd] shortcode on the front page, however I can’t see any problems. It could be that it only happens under very specific circumstances (how are you actually using it – in a static front page, embedded in a template with do_shortcode(), some other method?) or it could be more complicated then a conflict between just our two plugins – it might only exist with your particular theme or when some other plugin is active.

Right now I’m afraid I can’t see the problem so there isn’t a huge amount I can do here.
