Hi,

I have a problem with the Sendinblue Plugin. When I try to activate it from the settings and apply the changes, my Mautic installation crashes and display me the message “The site is currently offline”.

The plugin : [GitHub - dazzletheweb/mautic-sendinblue: Mautic plugin to enable sending via the Sendinblue API and receive statuses via webhooks.](https://github.com/dazzletheweb/mautic-sendinblue)

Thanks in advance.
