    Well, each error gives you explanatory message, what doesn't make sense? It would help you gave you a link to view your theme in action. Also, if you've submitted your theme, what does your reviewer say? If you haven't, have you emailed the theme review list for clarification on rules you don't understand?

  • No i haven't submitted the theme neither emailed these errors to theme reviewer, the market place for which i am working don't tell that how to solve these issues or any clarification regarding the errors. It just say that you have to resolve your errors which theme check generates..

  • These problems are pretty basic, it's telling you that themes that you submit are not allowed to use these features. You need to either change the way it's being done. Most of the time it is telling you what you need to use instead.

  • As-written, this question is a debug/QA my code/work-for-me-for-free question, and omits relevant code. Please review the WPSE FAQ for guidance on how to write good-quality questions.

File operations should use the WP_Filesystem methods instead of direct PHP filesystem calls.

The WordPress coding styles require that you make use of the WP Filesystem instead of using direct PHP file functions. You can replace your file_get_contents call easily with:

$response = wp_remote_get($feed_url);
$file_content = $response['body'];

For more specific infos just take a look at: "A Look at the WordPress HTTP API: A Practical Example of wp_remote_get".

If the file you want to read is not a local file, then please refer to the WordPress Filesystem_API.
