Hi,

Please make check the points below:

1/ Make sure you're using latest version of the theme & plugins from the theme.

If not, please remove the code at the end of functions.php file like on this image: http://prntscr.com/uon4qx ( if you don't see it, you can ignore this step ) 

After that, do following this guide to get auto-updates the theme: https://pencidesign.ticksy.com/article/15633/

When the theme is updated - let's check it again.

2/ If point 1/ doesn't work, please try to deactivate all plugins ( except plugins come from the theme & Elementor plugin ) and try it again. If it works, let's enable each plugin to check what's plugin caused this issue. 

Best Regards,
