Magento 1 modules are handled inside the app/etc/modules/ folder of your website. Make sure that both Mage_Newsletter and Mage_Widget is set to active. It is most likely that Mage_Widget is disabled.

Inside app/etc/modules/Mage_All.xml :

      <Mage_Newsletter>
        <active>true</active>
        <codePool>core</codePool>
        <depends>
            <Mage_Core/>
            <Mage_Customer/>
            <Mage_Eav/>
            <Mage_Widget/>
       </depends>
    </Mage_Newsletter>`

Inside app/etc/modules/Mage_Widget.xml:

     <Mage_Widget>
        <active>true</active>
        <codePool>core</codePool>
        <depends>
            <Mage_Cms />
        </depends>
    </Mage_Widget>`

Clear cache afterwards : rm -rf filelocation/var/cache/*
