Getting a PHP error

Hi, I’m trying to install latest version but I’m getting this error attached.

I have resell hosting with Bluehost and running the invoice system from sub-folder.


I don’t think that this error is related to InvoicePlane as it does not use the Oauth library. Please consider searching on Google for a proper solution.

Hi, now this error, but my php version is 5.6

This error is related to your hosting provider who is using an old version of PHP.
You should contact Bluehost.
