Hello,
1) Password is incorrect and we can’t log in to your Dashboard http://prntscr.com/vdhz3o
Please, check and provide the correct one.
2) Go to Plugins > disable the XStore core plugin and remove it. Go to XStore > Plugin installer > install plugin again. Check the menu after that.
3) I see the slider on the home page http://prntscr.com/vdi0st Provide screenshot of elements where you added the links for better understanding.
Regards
