Import CSV in Wordpress Multisite

[INA2N]

When trying to import a small CSV file into a Sendpress subscriber list, the results are null. After the file is selected, and then Upload, the results take you to the original page as if nothing happened.

Running backtrace_errors on the site, you can see the results below for both before and after the import attempt.
