Hello, Natasa,
Thank you for providing us with temporary wp-admin and FTP access. We have thoroughly reviewed your website and found that both the XStore theme and the XStore plugin are functioning normally. It is important to note that the plugin and theme offer a wide range of features, which inherently increases the load on your system.
Should you have any more questions or require further assistance, please do not hesitate to reach out.
Best Regards,
8Theme’s Team
