Issue: Create new button not showing dropdown

Your wiki is requiring me to login but it is probably related to this page not working:
Currently that URL returns a 500 error. Please look into that error for more information about what the problem is. Is yui_loader.php present? Is a PHP error occurring? Is your server trying to serve the resource statically because it ends in .js?

I'm loading this link just fine, getting a blank page with no errors.

I've given unregistered users view access. I have also found that the create new dropdown isn't the only one that doesn't work. Options and view tabs on each page also don't work.

First, make sure that the file vault/config.php exists. If you only see files with an extension like vault/config.php.xf, you must rename it to vault/config.php. If this file does not exist, yui_loader.php will throw an error.

This is the only other thing I can think of without information from your logs. I have visited your site as a guest and I can confirm that the issue you are having with the drop-downs is being caused by 500 Internal Server errors that occur during every variation of yui_loader.php. You can see the same activity in the Network tab of Chrome's DevTools view when visiting your wiki. You will need to review your server's logs to find out what the full error message is during yui_loader.php, as I would have no idea how to assist you without having that information.

Thanks. Renaming config.php.xf to config.php solved the problem.
