i'm trying to create a modification of the footer Joomla copyright default module. I'm creating a template languge override, but this does't work very suitably,
i would like to know how to edit the text displayed in the footer
Your screenshot makes no sense, that's not the right place to override a module.
The Joomla footer module (
modules\mod_footer) is a simple module that basically outputs some lines of text, and if you want to modify the output, the simplest solution is to add a
Custom module from your module manager:
Publish the module to the same position as your footer module, and unpublish the current one.
If you prefer to use the
mod_footer module, you can override the output by copying the file
ROOT\templates\YOURTEMPLATE\html\mod_footer\default.php. Edit the file to suit your needs.
