Installed it to improve my site security. The interface is simple, and most features work well. Had to tweak a few settings, but nothing complicated. Overall, pretty useful plugin. tnx devs.
This plugin seems to be designed for SiteGround hosting only. I am using SiteGround, and the plugin works well except for the file whitelisting feature. I applied the sgs_whitelist_wp_content custom filter from the SiteGround documentation; while it resolved the Apache error, the file is still being blocked. This is a known issue for myself and others, specifically regarding the TranslatePress trp-ajax.php file.
This plugin has caused nothing but endless problems. It clashes with Elementor and Papal payment plugins. Of course, all Siteground do is blame the other companies, as if their plugin is perfect.
Worst of all it repeatedly asks you to consent to sending data to Siteground. There is no refusal box. So the box pops up every time you choose a different menu selection. It is a cynical attempt to get you tick the box, and allow them to abuse your data, to make it go away. I intend to report Siteground to the ICO for this invasive demand.
Excellent easy to follow info
fulfills its purpose completely, very good
