 * Hi, I was just testing PHP compatibility with PHP Compatibility Checker plugin
   and found that your plugin has some issues as below >
 * FILE: /public_html/wp-content/plugins/wp-hide-security-enhancer/compatibility/
   a2-optimized.php
    ———————————————————————————————————— FOUND 1 ERROR AFFECTING
   1 LINE ———————————————————————————————————— 43 | ERROR | “$this” can no longer
   be used in a plain function or method since PHP 7.1. ————————————————————————————————————
 * Also, in wp hive it shows this plugin is taking too much memory usage i.e. > 
   Average memory usage is 516.14 KB.
 * I hope you will solve these issues in future updates.
 * Thank you for this wonderful plugin.
 * And are you planning to support this plugin for 8.1 PHP version?

 * Hi,
    Thanks for your feedback. The notification issue will be fixed in the next
   plugin update. Regarding memory usage, this is really decent usage compared to
   other codes. Similar plugins require at least a few times more. Keep in mind 
   that only the WordPress framework itself uses at least 15Mb. Considering the 
   other popular plugins like WooCommerce, Elementor, SEO etc, the average memory
   consumption on a modern website requires a lot of memory. On average, these days
   a site runs on 512Mb hosting memory or more.
 * Thanks
