Anyone using the Komento Joomla extension should mosey over to StackIdeas official site and download a brand new hotfix to plug a few holes in Komento's code. Although rare, it seems that a serious bug has been discovered which can cause a site to crash if it is not fixed. Komento users can download the patch here. StackIdeas also offers the relevant source code for users to FTP onto their site if they're not interested in running a software patch. From start to finish, the patching process should take less than five minutes, so there's no reason to delay!
