So today we ran in a little issue with the WordPress using the MailPoet plugin.
It gave an error and we got it fixed. Solution was not to hard 🙂

The fix to get that plugin to run is:
1. open Portainer and go to your container containing the website.
2. connect to the console
3. run these commands in the console:
apt-get update
apt-get install -y libzip-dev zlib1g-dev
docker-php-ext-install zip mysqli pdo pdo_mysql
a2enmod rewrite
4. Disconnect and restart the container.

And you should be fine 😉
