Problem with Enfold and user-activity-log-pro

Dear Enfold-team,

thanks for the wonderful Enfold Theme. Since I found it I already purchased many licences for different projects and recommended it to whomever talks about creating something with WordPress.

Today I have a problem that seems serious (for me):
– Installation is latest WordPress 5.1
– Network mode with subfolders
– Enfold 4.5.2
– Plugin user-activity-log-pro

The only network site I want to track is not done with Enfold, but with one of the WP standard themes. It’s a closed area where users have to log in, and these users are tracked.
However: It seems the user-activity-log-pro plugin is a global plugin, but I’d love to use it only for the non-enfold network-site.

Behaviour with previous Enfold installations:
——————
I receive the same error messages, but surpressed them with WP-config parameters.

Behaviour with NEW Enfold network site installation:
—————–
Although having deactivated the error message delivery, I receive this messages:

Warning: in_array() expects parameter 2 to be array, boolean given in /kunden/salvamundo.com/webseiten/certista.com-enfold-4-5/wp-content/plugins/user-activity-log-pro/includes/ualp-hooks.php on line 292

and

and

My Question now:
Is this an enfold problem?
Is this the plugin problem?

I would love to exclude the plugin from the enfold sites as I don’t need tracking for public sites.
Or alternatively I would like to change the behaviour.

It is strange that on one site it works, but on the other one it does not (the one installed later gives an error).

Do you maybe have any idea what I can do?
Maybe also adapt Enfold settings somewhere in the database?

Thanks a lot for any help!
Tobias
