I've installed a new version of concrete5 v8.3.2 and it appears to be working fine, but every time I try installing the Stucco theme (with sample data) I get an Internal Server Error.

I am selecting the option "Yes. Reset site content with the content found in this package". If I select "No", the install works, but I'd like to get see the sample content to better understand how the elements are set up.

Any ideas what the issue could be? Here is my environment info
