Resource version not set in call to wp_register_script(). This means new versions of the script may not always be loaded due to browser caching.

Sample message

In footer ($in_footer) is not set explicitly wp_register_script; It is recommended to load scripts in the footer. Please set this value to `true` to load it in the footer, or explicitly `false` if it should be loaded in the header.

Sample message

Translatable string should not be wrapped in HTML. Found: &#039;&lt;p&gt;The minimum acceptable size can be set for featured images. This size means that posts with images smaller than the specified dimensions cannot be published. By default the sizes are zero, so any image size will be accepted.&lt;/p&gt;&#039;
