Where do I find this text

[SEE]

<?php
                        }
		
                        if($edit) {
                            ItemForm::plugin_edit_item();
                        } else {
                            ItemForm::plugin_post_item();
                        }
                        ?>
          <div class="form-group">
            <?php if( osc_recaptcha_items_enabled() ) { ?>
            <div class="recap">
              <?php osc_show_recaptcha(); ?>
            </div>
            <?php }?>
            <div class="controls">
              <button type="submit" class="btn btn-success">

The button works fine with 2 of 3 themes, on the 3rd there is missing the text inside the button "

Where do I find the word “Publish” where does it take from? CSS ?

Where is the class defined in your CSS?

Either way, I don’t think it looks like a PHP issue, even if the code does include some PHP for other things.

Use your browser’s inspect feature.

When you mention themes, are you using WordPress, or another CMS?

it is a OS CLASS theme,… I did a update of the files, and it solved. Thank you all for your help !
