Accounts Group and Accounts cant be added.

Thank you Arteeq for the new build, have managed to install it, unfortunately though it installs and logs in successfully with out any issue, the challenge I'm now facing the system stops working on adding companies, when I select comapny and try to add Accounts or Accounts groups the submit button is not saving anything. plus logging in using subscriber account there is two menus but both refering to files that are missing (all.php and subscriber.php)

After creating a subscriber account you have to provide a company access to that subscriber. You can only provide full company access to a subscriber not indvidual account or any other option. So after creating a subscriber user go to Companies >> Company access and grant him/her access. 

About groups they are being added just fine at our end, please check your console for any errors. What is your PHP version and turn off the PHP notices, warnings as well. 

Thank you Samar for quick response, changed from Wamp to Xampp and the group/account issue disappeared. System now is working fine except the bug listed below. In the screenshot below when a subscriber account logs in, the red circled menus are referencing to non existing files hence have failed to post transactions through subscriber's account. kindly assist.

okay there was a problem with it i got the script updated please find attached and update your installation except your db_connect.php then General Ledger would start working fine thanks.
