Q:

How to Remove Welcome Message bar in MAGENTO

I have gone through all tutorials online and unable solve the problem.
I am using magento in my Website, and I can't remove the welcome message bar. From configuration if I set welcome message box empty the welcome bar still shows, their must be some coding to do that.

A:

Navigate to file app/design/frontend/rwd/default/template/page/html/header.phtml and comment next lines:
<div class="header-language-background">
    <div class="header-language-container">
        <div class="store-language-container">
            <?php echo $this->getChildHtml('store_language') ?>
        </div>

        <?php echo $this->getChildHtml('currency_switcher') ?>

        <p class="welcome-msg"><?php echo $this->getChildHtml('welcome') ?> <?php echo $this->getChildHtml('accountLinks') ?></p>
    </div>
</div>

After that remove cache. Hope, this should help.
