Opera will not load Cufon if there is even 1 empty or 404 stylesheet & with easy post types activated there are 5 stylesheets included with the wrong path.
If you need to Fix this(all other browsers seem to be more forgiving about this), FTP to wp-content/plugins/easy-post-types/classes
You have to edit each file listed here:
custom-checkbox/custom-checkbox.php
custom-checkbox/custom-datefield.php
custom-checkbox/custom-image.php
custom-checkbox/custom-select.php
custom-checkbox/custom-textfield.php
In each file you find this line(Sorry Line # are not the same):
wp_enqueue_style($this->getId().'-style', $this->root. 'style.css');
Change it to
wp_enqueue_style($this->getId().'-style', $this->httpRoot. 'style.css');
The author defines root and httpRoot
$this->root=dirname(__FILE__).'/';
$this->httpRoot = plugins_url( '', __FILE__).'/';
I opened the main plugin file custom-type.php
and noticed scripts were included correctly if using httpRoot
so I put 2 and 2 together.
Now Opera loads Cufon.
