I just install PHPBB from scratch along with PPDE, and when I enter in "extensions" page on ACP, I can't access "Overview" and "General Settings" options of PPDE, I get an browser's "This page is not working" message. "Donation Pages", "Currency Management" and "Transaction Log" works fine though.
phpbb version: 3.2.0.
ppde version: 1.0.2.
PHP Version:
PHP 7.0.14-2+deb.sury.org~xenial+1 (cli) ( NTS )
