Some issues

Hi,

simple-post-notes.php, Line 466, its code should be the following. The text domain of this button text should be fixed.

<?php submit_button( __( 'Save', 'simple-post-notes' ), 'primary', 'save' ); ?>

Text Domain loading issue as the following.

Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the simple-post-notes domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later.
