 * After a client start experiencing issues with their website, I discovered in 
   the access + error logs that this plugin was flooding the website with hits to
   the URL:
 * /?ob=open-bridge/events
 * repeating literally seconds apart, each giving an internal server error with 
   the stack trace (sanitized below):
 *     ```wp-block-code
       PHP Fatal error: Uncaught FacebookAds\Http\Exception\AuthorizationException: Error validating access token: Invalid session for app in xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Http/Exception/RequestException.php:174Stack trace:#0 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Http/Client.php(226): FacebookAds\Http\Exception\RequestException::create(Object(FacebookAds\Http\Response))#1 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Http/Request.php(286): FacebookAds\Http\Client->sendRequest(Object(FacebookAds\Http\Request))#2 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Api.php(152): FacebookAds\Http\Request->execute()#3 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Api.php(205): FacebookAds\Api->executeRequest(Object(FacebookAds\Http\Request))#4 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/ApiRequest.php(171): FacebookAds\Api->call('/xxx...', 'POST', Array, Array)#5 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Object/AdsPixel.php(292): FacebookAds\ApiRequest->execute()#6 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/EventRequest.php(284): FacebookAds\Object\AdsPixel->createEvent(Array, Array)#7 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/EventRequest.php(277): FacebookAds\Object\ServerSide\EventRequest->defaultExecute()#8 xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Object/ServerSide/EventRequest.php(247): FacebookAds\Object\ServerSide\EventRequest->sendToCAPIEndpoint()#9 xxx/wp-content/plugins/official-facebook-pixel/core/class-facebookserversideevent.php(197): FacebookAds\Object\ServerSide\EventRequest->execute()#10 xxx/wp-content/plugins/official-facebook-pixel/core/class-facebookwordpressopenbridge.php(162): FacebookPixelPlugin\Core\FacebookServerSideEvent::send(Array)#11 xxx/wp-content/plugins/official-facebook-pixel/facebook-for-wordpress.php(124): FacebookPixelPlugin\Core\FacebookWordpressOpenBridge->handle_open_bridge_req(Array)#12 xxx/wp-includes/class-wp-hook.php(324): FacebookPixelPlugin\FacebookForWordpress->handle_events_request(Object(WP))#13 xxx/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters('', Array)#14 xxx/wp-includes/plugin.php(565): WP_Hook->do_action(Array)#15 xxx/wp-includes/class-wp.php(418): do_action_ref_array('parse_request', Array)#16 xxx/wp-includes/class-wp.php(818): WP->parse_request('')#17 xxx/wp-includes/functions.php(1342): WP->main('')#18 xxx/wp-blog-header.php(16): wp()#19 xxx/index.php(17): require('xxx...')#20 {main} thrown in xxx/wp-content/plugins/official-facebook-pixel/vendor/facebook/php-business-sdk/src/FacebookAds/Http/Exception/RequestException.php on line 174

 * This resulted in the webhost’s entirely monthly bandwidth allowage being used
   in a few hours.
 * Obviously there was some issue with the connection between your plugin and Facebook,
   but not matter what the cause is, the plugin should never fail in this disastrous
   and expensive way.
 * The lack of error checking means this isn’t a plugin we’ll be using again.

 * Hi [@smerriman](https://wordpress.org/support/users/smerriman/) ,
 * We are sorry you are having issues with the plugin. Can you try the following:
    - Temporarily disable any cache plugins you’re using and clear the cache
    - Go to the Settings > Meta page, open the “Connection Settings” tab and Delete
      the connection
    - Reinstall the Meta pixel for WordPress plugin
    - Re-connect your site with the plugin
 * Kind regards,
   Marija

 * I can’t do that as the plugin has been deleted 🙂
 * As mentioned, the problem is not that there may be a workaround to solve it, 
   but that any properly written plugin should NEVER result in this behavior – it
   should have error checking to prevent this.
