Hello Sir, I have identified the cause of the problem. It appears to be a conflict with another plugin, ‘WP Hide & Security Enhancer’. When I deactivate this plugin, the ‘Access’ feature works. However, when the plugin is activated, the ‘Allow Access’ feature does not work. I have tested all the functions of the WP Hide & Security Enhancer plugin and disabled all its features while keeping the plugin activated. This means that even when the plugin is activated and no active functions are serving my website, the error still persists on the WordPress Download Manager. The ‘Allow Access’ feature works fine when the WP Hide & Security Enhancer is completely deactivated. Please help me fix this issue so that these two plugins can work together without conflict. This error persisted when WordPress was updated. Previously, I had no issues between these two plugins. Thank you.
