Run security plugin-check and fix ERRORS

[asirota]

I have checked the following:

• I use the newest version of WildApricot Press.
• I've searched existing issues and found nothing related to my issue.

WildApricot Press version:

1.1

Describe the bug

Run /wp-admin/admin.php?page=plugin-check on PLayground and look at Security errors. These need to be fixed
