[Bug Report] Update client information

[member_6833]

Hi WHMCS Service,

There are some bugs existing in Client Username's module:

1. If we inspect website (F12), remove "disabled" in the username field, then user can edit their username whatever we allow them or not.
2. If clients update their information with username field disabled, then their username will be changed to blank

Two bugs are very critical. Please fix it soon as possible,

Thanks,
