Hello Michelle,

First, could you please try reinstalling s2Member and s2Member pro? Uninstall them and install them again. Make sure to have deactivation safeguards on though, so that you don’t lose any settings: Dashboard -› s2Member® -› General Options -› Deactivation Safeguards.

If that doesn’t fix it, could you please try these common trouble shooting tips, all of them: Knowledge Base » Common Troubleshooting Tips

Thanks for reporting this important issue.

Yes, I would also suggest a reinstall of s2Member Pro (e.g. delete your current installation files, and upload a fresh copy of the latest release). The file that you referenced does not exist in s2Member Pro, which would lead me to believe that your current installation has been corrupted in some way.

You referenced file:
s2member-pro/includes/functions/._api-functions.inc.php

This file should be named:
s2member-pro/includes/functions/api-functions.inc.php

Please be sure to follow the instructions that we’ve provided here:
s2Member® » Pro » Install/Upgrade Instructions

Please let us know if problems persist :-)
