Testing with twenty-eleven theme & no other plugins installed
In the admin, at the top I get the notice:
Notice: Undefined index: action in /.../wp-content/plugins/amazon-product-in-a-post-plugin/inc/amazon-product-in-a-post-options.php on line 154
& four instances of:
Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in /.../wp-includes/functions.php on line 3551
Also many notices within the input fields in the Amazon PIP options page:
Notice: get_settings is deprecated since version 2.1! Use get_option() instead. in /.../wp-includes/functions.php on line 3467
Thanks for the information.
The deprecated items are already set to be updated in the next version. The Undefined index item I will look into and add it to the next version update fix list.
In the next version, the plugin will set a custom capability so that admins can turn it on or off more easily for different user levels and override the plugin default settings. It will also be easier to turn the plugin on/off for custom post types and allow for Super Admin capabilities on WordPress multi-site installs.
