Some themes in WordPress (like this one) only allow an image logo in place of a title.
Here is a quick way to replace that image by a text title using jQuery:
1- Install the WP-Headmaster plugin.
This is a great way to allow more control over the header of pages in your WordPress site, including injection of jQuery code.
2- In WP-Headmaster settings, under the ‘scripts’ tab, set the first option to No influence and copy this code in the script text area:
jQuery( document ).ready(function() {
jQuery( 'img#logo' ).hide().after( "<span style='font-size: x-large; font-weight: bold;
display:inline; padding-left:10px;'> My Title </span>" );
});
Note that the identifier for the logo to replace can change from theme to theme.
