We’re excited to present you Onthos, our new extension which will change the way you manage your site's extensions.
What Makes Onthos Stand Out
Joomla's built-in extensions manager is fantastic at installing, uninstalling, enabling, and disabling extensions… as long as everything on your site is in the pristine and ideal state it expects. What happens in a real-world site is a different, messier story.
Ever got Joomla to complain that it cannot update because you have “incompatible” extensions, only to find out these were supposed to be part of a package but don't appear as such? Ever had old, obsolete extensions you can no longer uninstall because their installation script is no longer compatible with your Joomla and PHP version? Ever had leftovers in your #__extensions table which Joomla can't remove because these extension files don't exist anymore? Ever had extensions missing database tables or files, but had no way to easily find out?
These, and many more issues, plague real-world sites. We get it. We deal with real-world sites on a daily basis. It gets complicated. Files get moved around. Backups with newer (or older) versions of your site are installed over an existing site. Databases crash. People make mistakes. Browsers, like Safari, mislead users into installing package extensions the wrong way. We could go on forever.
This is why we created Onthos. It can detect all extension issues we have run across in real-world sites over the last two decades. Most importantly, it can fix them, and most of them automatically. When an automatic fix is impossible, it will give you simple, clear instructions on what to do. And, yes: it can uninstall any extension, even the old ones, and the leftovers you have not been able to remove from your site!
