An Internal Error Has Occurred

<p>Hello. I successfully installed FlinkISO along with OnlyOffice on an Ubuntu Server. I proceeded to create an Employee then a User account since the system only allows account creation following that order. The created user receives their credentials via the email address associated with their account and they are able to log in. The Internal Error comes in when navigating to the Employees section as an admin. Below is the detailed message of the error.log:</p><p><br>Error: [TypeError] count(): Argument #1 ($value) must be of type Countable|array, false given<br>Request URL: /flinkiso/employees<br>Stack Trace:<br>#0 /var/www/html/flinkiso/lib/Cake/Controller/Controller.php(1112): PaginatorComponent-&gt;paginate()<br>#1 /var/www/html/flinkiso/app/Controller/EmployeesController.php(54): Controller-&gt;paginate()<br>#2 [internal function]: EmployeesController-&gt;index()<br>#3 /var/www/html/flinkiso/lib/Cake/Controller/Controller.php(500): ReflectionMethod-&gt;invokeArgs()<br>#4 /var/www/html/flinkiso/lib/Cake/Routing/Dispatcher.php(193): Controller-&gt;invokeAction()<br>#5 /var/www/html/flinkiso/lib/Cake/Routing/Dispatcher.php(167): Dispatcher-&gt;_invoke()<br>#6 /var/www/html/flinkiso/app/webroot/index.php(115): Dispatcher-&gt;dispatch()<br>#7 {main}&nbsp;<br><br>&nbsp;</p><p>Another issue is the newly created user is able to edit the Profile of the admin account but they don\'t inherit his/her admin privileges. For example, changing the personal telephone number while logged in the created account also changes the personal telephone number on the admin account however the created account is unable to view the Users and Employees sections since they lack the privileges.</p>'
