Uncaught SyntaxError: Unexpected token o in JSON at position 1

Hi Guys,

I recently installed WallacePOS.

Once installed I login as "admin" and Under "Settings->Staff&Admins", try to edit default username "staff".

Here when I click "Update" it's showing me following error. Uncaught SyntaxError: Unexpected token o in JSON at position 1 at JSON.parse () at WPOSAdmin.sendJsonData (wpos.js:431) at saveItem (eval at globalEval (jquery-2.0.3.min.js:4), :249:22) at HTMLDivElement.click (eval at globalEval (jquery-2.0.3.min.js:4), :82:25) at HTMLButtonElement.s.click (jquery-ui-1.10.3.full.min.js:7) at HTMLButtonElement.dispatch (jquery-2.0.3.min.js:5) at HTMLButtonElement.y.handle (jquery-2.0.3.min.js:5)

After I research, In wpos.php the error is happing at $cleanData = $purifier->purify($_REQUEST['data']);

Any advice or idea please let me know

Regards,

Raj
