404 errors

I installed this plugin and got a 404 for the events I had created. Disabling plugin organizer didn’t help. Clicking save on the permalinks page fixed it but every event I create after that does the same thing and I have to click save on the permalink page for it to work. The problem is in the sugar calendar plugin. When they register their custom post_type they need to call flush_rewrite_rules( false );. Then it works. I added that code to line 45 of /wp-content/plugins/sugar-calendar-lite/includes/post-types.php and the problem is fixed. Please contact the author of the sugar calendar plugin and have them add that code to their file.

You can test the fix out on your local copy of the plugin. It won’t fix the events you have already created though. Only new ones. Click save on the permalinks page to fix the events you have already created.

Awesome, that worked a treat, thanks!

I also have the same problem with my directory – it is a premium plugin which i can send to you if required?

Alternatively, is there something i can add to my functions.php file etc that will add this flush rule site wide?

This must be called directly after registering the post_type. The plugin author needs to update their code. I came across this bug a few years ago and now always add the call to flush_rewrite_rules after registering a custom post_type. You can go through the plugin code and find the register_post_type call if you want. Then just add that code after it.
