error caught by wordpress

[wocmultimedia]

Hi,
I'm running a site with wordpress 5.2.2. and I received a message that your plugin is creating an error.
Please, verify the compatibility with this wordpress version.
Actually, I haven't seen a visible error. It happened first time one month before I couldn't access the site but this time I succeeded to access my site regularly. Nevertheless, I deactivated it.
The website is https://www.mappeattive.com/
Regards,
Angelo
