Pliugin causes multiple bugs/crashes on the website. Customer support is absolutely not responsive/inexistent. I do not recommend this item. You'd better look for alternatives

Sorry for not responding in the holidays. The last request you sent me was a question if I can help you setting up the plugin for a fee. I'm afraid I can't provide that.
The only "bug" report you sent me was a PHP notice generated by another plugin. On the one hand, this is not a bug and on the other hand, PSN is not responsible for it.
