You just need to update theme to version 6.3.9.1 and XStore core plugin to version 2.3.9.1. Once you provide us with correct WP Dashboard access (because link you provided does not work http://prntscr.com/u0x9en ) and FTP we’ll help you with theme update. In addition, we would suggest to update all the bundled plugins (XStore > Plugin installer)
Also, we plan the new 7.0 theme update soon with redesign of the Dashboard and a number of optimization options.
