HashOver is a PHP comment system intended as a replacement for services like Disqus. HashOver is free and open source software, under the GNU Affero General Public License. HashOver adds a "comment section" to any website, by placing a few simple lines of JavaScript or PHP to the source code of any webpage. HashOver is a self-hosted system and allows completely anonymous comments to be posted, the only required information is the comment itself.

hashover.phpis no longer used in JavaScript tags, the file/hashover/comments.phpis used instead.So change:
<script type="text/javascript" src="/hashover.php"></script>
To:
<script type="text/javascript" src="/hashover/comments.php"></script>
-
The
pagesdirectory is nowcomments/threads, this change will cause existing comments to not appear until you move the directories underpagesinto the newcomments/threadsdirectory. -
All JSON config files have been moved to the new
configdirectory, you will need to move the fileshashover/blocklist.jsonandhashover/ignored-queries.jsoninto the newconfigdirectory. If these files do not exist, you don't need to do anything as these config files are completely optional. -
The previously removed
secrets.phpfile has returned. The required setup information, namely the notification e-mail address, encryption key, and the admin username and password are now stored in thissecrets.phpfile located at/hashover/backend/classes/secrets.php.You will need to move the values of the public properties
$notificationEmail,$encryptionKey,$adminName, and$adminPasswordin thesettings.phpfile into the new protected properties in thesecrets.phpfile, and remove these properties fromsettings.phpor replace thesettings.phpfile entirely, as its source code is publicly viewable, whereas the source code ofsecrets.phpis not.
Windows will be officially supported by HashOver 2.0, there should not be any major issues with using HashOver on Windows. However, HashOver is primarily developed on and for UNIX operating systems, which are the primary operating systems used by the majority of web servers. If you have any issues with HashOver on Windows, please report them.
