Closed manasmanohar closed 4 years ago

manasmanohar commented 4 years ago

Instascan had been working perfect couple of months ago,

but now the video feed of the scanner doesn’t appear, nor the scanning happens. The webcam lightups when i scan.

(Camera permission is asked , and the webcam light up). Havn't made any changes to the program, need a quick solution.

using it to scan qr code and paste the result to search field. hosting my site on cpanel,this is the error i cam across
