 * The compatibility checker tool for php of the “SG Optimizer” plugin (The cache
   plugin of SiteGround hosting company) shows the following issue:
 * FILE: /***/plugins/block-bad-queries/block-bad-queries.php
    ——————————————————————————————————————————————————
   FOUND 1 ERROR AFFECTING 1 LINE ——————————————————————————————————————————————————
   49 | ERROR | The behaviour of hexadecimal numeric strings was inconsistent prior
   to PHP 7 and support has been removed in PHP 7. Found: ‘0x3c62723e’ ——————————————————————————————————————————————————

 * Glad to help. Actually the “SG Optimizer” is incorrect in this case. The recognized
   pattern, `0x3c62723e` is not functional code; rather it is static text that is
   used as a BBQ pattern. So the plugin is able to block any malicious requests 
   that include it. So totally safe in this particular context. May want to let 
   the SG Optimizer plugin developer know about it, maybe there is a way to distinguish
   between static and live PHP code while scanning. Either way thanks for the feedback.

 * Thanks for your answer Jeff.
    Apparently there are so many false positives with
   SG Optimizer plugin. I have already open a new topic to inform about this: [https://wordpress.org/support/topic/php-false-positive-block-bad-queries-plugin/](https://wordpress.org/support/topic/php-false-positive-block-bad-queries-plugin/)

 * Yeah it’s just the nature of the beast when it comes to automating code analysis.
   Thanks for opening the new topic, hopefully they are able to help with all the
   false positives, etc.
