## Troubleshooting
**Cause**: Incorrect password or expired account
**Solution**:
1. Check that you entered the password correctly
2. Check that Caps Lock is not on
3. Ask an admin to check your account status
**Cause**: Menus are restricted by account role
**Solution**:
* Retailer accounts can access only placement-related menus
* Advertiser accounts can access only campaign-related menus
* If you need additional permissions, ask an admin
**Cause**: Insufficient admin permissions or invalid input format
**Solution**:
1. Check that you are signed in with an admin account
2. Enter numbers only for the amount (no currency symbols)
3. Refresh the page and try again
