Error 500 after installing FB SDK

[fsopm]

Hi there,
thanks for your work.

I have tried to install the plugin but I'm stuck at the fist step.
I have well installed the FB SDK but then, Mautic is not available.

Here is the error log:

[13-Jan-2020 15:19:01 UTC] PHP Fatal error:  Uncaught Error: Class 'Mautic\ApiBundle\MauticApiBundle' not found in /home/XXXXX/public_html/app/AppKernel.php:169

Have you ever faced that kind of issue?
I use the version 2.15.3 of Mautic.

Thanks

Hello did you manage to solve the integration problem?

Hi @consultor360,
not at all and moreover, it seems it broke our mautic installation.
After the install of the module, our subscribers received the same campaign email more than 5 times.
