At SiteGround, we have created toolkits for WordPress and Joomla! which automate the most common admin tasks, like resetting the admin password, moving or deleting your site, changing domains, fixing permissions and others. To access the admin toolkits, log into your User Area → Manage Accounts → Go to cPanel. You can open the toolkit shortcuts from the two corresponding sections: WordPress Tools and Joomla! Tools.
