We have a platform for buying and selling college notes. We use the Scribd API as an online document repository to view the note. Currently we are having an error when uploading the note or previewing any one that was previously uploaded. The site was working well, and now the error keep showing.
I need someone to either solve the error problem or find another solution that we can use instead of the Scribd API that can work in the PhP environment.
TO check the the site:

and click on "preview" on any of the notes in the home page table
