Hi Nelson,
Something you have changed inside the functions.php so that you are getting this syntax error. So you reinstall this theme again so that you will get rid out of this problem. If you get still same problem then please feel free to send message for us.
I was trying to find out how to allow a full width screen display then this happened:
–> We have the options to display full width with no sidebar inside dashboard -> appearance -> theme options -> content layout
Select full width no sidebar.
IF you want to display all the theme in full width then you need code customisation for it. You have to customise the code for responsive design too. So you may hire a developer to fix the issue.
Thank you!
