I recently purchased a plugin called Ajax Cart for HTML websites with Digital Products. Regular License.
I tried installing but got an error. I cannot remember exactly. But it was along the lines of ‘call to undefined function password hash on line 149’. The line is approx, I remember that! I Googled it and I figured it is my Php MySQL database which only uses PHP 5.5… If there is a work around I would love to hear it. Otherwise I am a bit clueless on how to refund. It isn’t easy to find!
