CommunityAuth

Perhaps you can make a zip of your entire website files, and include a database dump, then make it available for download so I can check it out.

Maybe I can try to do that later, but I'd like to learn what I'm doing wrong.   I've read your instructions many times and curious about 4, 5, 6 & 11.

You use the word "Copy" which means;
4. having a file remaining in community_auth/core AND another new file in CodeIgniter’s application/core directory, 2 files in total.
5. having a file remaining in community_auth/hooks AND another new file in CodeIgniter’s application/hooks directory, 2 files in total.
6. having a file remaining in community_auth/controllers AND another new file in CodeIgniter’s application/controllers directory, 2 files in total.

or do you mean "Cut" or "Transfer" and having only the new files in the CodeIgniter's directories, 1 file in each directory?   I have tried deleting the community_auth files but it makes no difference.

Another area where I suspect maybe causing the error is the failure to set the encryption key.   11. Enable hooks and "make sure there is an encryption key set" in config/config.php.   I enabled the hooks but I'm confused about setting the encryption key.

Undoubtedly I'll need to learn how to encrypt data at a later stage in the development process.

I've read "Setting your encryption_key" in the user_guide\libraries\encryption.html and wonder why an encryption key can not be set at a later stage of development, and be left blank in the meantime.

Or can I just enter any 16 characters into $config['encryption_key'] = ''; for the meantime?
