Problems loading the page

I’m having trouble loading the page with the Rookie theme.
If I change the theme to any of the WordPress repository the web loads without problems, now when I load the Rookie theme it tells me that there is a memory problem and it does not load the web or any section.

I already deleted the issue from the FTP, I reloaded it and it continues with the same problem, what can be the solution?
