access_token throwing error invalid sinature or token

[vimal]

Hello Guys,

I am requesting for acces_token working with php.

I got error invalid signature or token 'Rknse1PC6xh93HEki7461b7tCY0=' or token '1ba7e2d6ad40019cd79280a13b9e4e40'.

please suggest me what to do.

Can you tell us more about the OAuth client you are using, the base string being generated, etc?
