 * After installing plugin I can not get the merchant to authenticate through the
   API.
 * I have followed the installation instruction correctly and insured I have the
   latest versions of PAP & WP as well as moving the PapApi.class.php to the proper
   location.
 * I have emailed [jsimon@qualityunit.com](https://wordpress.org/support/topic/plugin-post-affiliate-pro-install-issues/jsimon@qualityunit.com?output_format=md)
   with login info and FTP.
 * Thanks for your help!

 * When you install the PAP-WP plugin, oftentimes there is an error in the header
   of the plugin.
 * I’m not sure Quality Unit is going to support this – but they might. I know the
   developer is friendly to work with but since he doesn’t make any money from the
   sale of the plugin, he can be slow to get the bugs worked out.
 * I have found the solution by opening up the individual files in the plugin folder
   and 1-by-1 installing them in the /plugins/pap folder – using only the files 
   necessary. (Without going through the motions again, it’s hard for me to give
   specific instructions but I’ve used this twice before and it has worked.)
 * But the answer to your problem is in the header files of the plugin; generally
   not the API (although there was a bug fix with the API recently but if you say
   you’re using the most recent version, this should not effect you either way).
 * So try uploading only the plugin files you need to the wp /plugin/pap folder 
   and hopefully this will take care of your issue.
