Hello Haitham Alhendal,
Thank you for the details. We have installed the same plugin package you downloaded on your website without any issues. Probably the plugin was not downloaded properly and so you faced the issue.
We have tested the buttons for the two issues mentioned above and found working.
1) The button on single product page not working (resolved)
2) Button don’t have pointer on hovering (resolved)
Best regards,
INTOLAP Support
