xF1 Add-on Inactive Members 4.1

On Jan 1, 2016 version 3.3 of this add-on was released to address an exploitable SQL injection vulnerability. If you are still using a version of this add-on which is below 3.3 or released before Jan 1, 2016 then it is essential that you update to the latest version of the add-on as soon as possible to fix this security issue.

Inactive Members v4.1 changes:

1) Emails are sent only if there are new threads.
2) Phrase updated.

Inactive Members v4.0 changes:

Added option to add image to email.

Inactive Members v3.9 changes:

Corrected a typo in the Options page.

Inactive Members v3.8 changes:

1) Removed no longer needed Route Prefix.
2) Added a check for valid Language ID.

Please note this add-on no longer supports running manually from URL. It will run by Cron Entry on the first of every month.

When upgrading I suggest deleting the entire Andy/InactiveMembers folder first that way you will not have any extra unneeded folders on your server.

1) Added ability to send a test email by adding User ID in Options page.
2) Emails are now mobile device friendly.
3) Removed seldom used functions to make using the add-on easier.

Fixed PHP code.
