# Cant insert scripts, JSON error

 * I cannot get 3rd party script to fire when the conditional is active. Troubleshooting
   I see that when the plugin is activated I get this JSON parse error in the logs
   implicating the named Moove plugin JS AJAX success action:
 *     ```
       jquery-migrate.min.js?ver=1.4.1:2 JQMIGRATE: Migrate is installed, version 1.4.1
       VM1534:1 Uncaught SyntaxError: Unexpected token < in JSON at position 1
           at JSON.parse (<anonymous>)
           at Object.success (main.js?ver=1.1.1:1)
           at i (jquery.js?ver=1.12.4:2)
           at Object.fireWith [as resolveWith] (jquery.js?ver=1.12.4:2)
           at y (jquery.js?ver=1.12.4:4)
           at XMLHttpRequest.c (jquery.js?ver=1.12.4:4)
       (anonymous) @ main.js?ver=1.1.1:1
       i @ jquery.js?ver=1.12.4:2
       fireWith @ jquery.js?ver=1.12.4:2
       y @ jquery.js?ver=1.12.4:4
       c @ jquery.js?ver=1.12.4:4
       XMLHttpRequest.send (async)
       send @ jquery.js?ver=1.12.4:4
       ajax @ jquery.js?ver=1.12.4:4
       n.(anonymous function) @ jquery.js?ver=1.12.4:4
       (anonymous) @ main.js?ver=1.1.1:1
       init @ main.js?ver=1.1.1:1
       fire @ main.js?ver=1.1.1:1
       loadEvents @ main.js?ver=1.1.1:1
       i @ jquery.js?ver=1.12.4:2
       fireWith @ jquery.js?ver=1.12.4:2
       ready @ jquery.js?ver=1.12.4:2
       K @ jquery.js?ver=1.12.4:2
       ```
   
 * You’ll notice the at Object.success (main.js?ver=1.1.1:1) … that’s the Moove 
   plugin. The triggering event being action:”moove_gdpr_get_scripts”,strict:e.strict,
   thirdparty:e.thirdparty,advanced:e.advanced} …
 * Consequently any basic 3rd party script will fail to fire due to that JSON error,
   for example a failing script:
 * <script>alert(‘test’);</script>
 * fails to write to the page, and fails fire in any position, head, body, footer.
 * I suspect that the JSON parse error is the cause.

 * Hi there,
 * Thanks for your comments.
    Could you please provide me more details about your
   website? PHP version, WP version, website-url to check the issue on your front-
   end?
 * Thanks

 * Hi there. This site is running
    PHP Version 5.6.3, WP version 4.9.6
 * the URL is currently a local dev server. I’m testing strategies for a client 
   before committing.
 * I think I have found that the issue, a clash with another plugin. Unfortunately,
   it is clashing with a plugin I wrote myself – a front-end registration and login
   plugin.
 * the offending line in MY plugin (triggering the JSON error in yours) is this 
   dashboard restriction and redirection for members. I’ll take a look at fixing
   my own error in this wonky looking action, but if you have any thoughts I’d welcome
   them.
 *     ```
       function pher_restrict_dashboard_to_admin() {
           if ( !current_user_can( 'manage_options' )  && $_SERVER['PHP_SELF'] != '/wp-admin/admin-ajax.php' ) {
               wp_redirect(home_url('/member-portal/'));
           }
       }
       add_action( 'admin_init', 'pher_restrict_dashboard_to_admin', 1 );
       ```
   
 * commenting out the //add_action in my plugin will allow your plugin to add scripts
   without any JSON errors

 * I have resolved my issue. I amended my function to
 *     ```
       function pher_restrict_dashboard_to_admin() {
         if ( is_admin() && ! current_user_can( 'administrator' ) &&  !( defined( 'DOING_AJAX' ) && DOING_AJAX ) ) {
           wp_redirect(home_url('/member-portal/')); exit;
         }
       }
       add_action( 'admin_init', 'pher_restrict_dashboard_to_admin',1);
       ```
   
 * and everything with your plugin works fine now. Sorry for the false alarm.
