PHP FATAL ERROR

Hi team.
I’m really fascinated with your plugin, Thanks !

Unfortunately, I am experiencing several Errors since I’ve installed and I don’t think it’s working like it should.

First one was when disabling “accounting” module.
After that, I could set up SMTP mail successfully, but when user sends a form, contact will not display properly in backend, instead, I could also see a fatal error there.

I can’t recreate some of the errors I’ve seen. These are the current errors I have right now:

When deactivating any of the 3 modules, in tools >> status: Screenshot

After setting STMP mail, and testing form . Screenshot

Mail I’ve recieved from WP:

WordPress version 5.5.1
Current theme: Digitalek Child Theme (version 2.2.1584467269)
Current plugin: WP ERP (version 1.6.6)
PHP version 7.2.33

Error Details
=============
An error of type E_ERROR was caused in line 311 of the file /home4/sebaeco/public_html/digitalek.com/wp-content/plugins/erp/includes/framework/class-system-status.php. Error message: Uncaught Error: Call to undefined function WeDevs\ERP\Framework\erp_hr_get_manager_role() in /home4/sebaeco/public_html/digitalek.com/wp-content/plugins/erp/includes/framework/class-system-status.php:311

I hope we can sort this out, since I really want to use this plugin. Also have seen premium addons, which I found expensive but very interesting.

Thank you
