I was so fed up with the regular "Read More" button titles and wanted to customize it to something more appealing and friendly. Here is how I changed read more button titles in Joomla 3.
Open your Joomla Administrator Page and navigate to Extensions > Language Manager
Select Overrides from left side.
Now click on New Button
Search for "Read more" text in the search box on the right
Now select "COM_CONTENT_READ_MORE_TITLE"
Now change the "Read More..."i text to your custom text, here we've changed it to Continue Reading... and click on Save & Close
Go ahead and test your site's front-end, it shall show up now. In case you do not see the changes, please clear the cache and reload the site.
