1.注释 app/etc/amfpc.xml文件中的cache

<!-- <cache>
            <request_processors>
                <amfpc>Amasty_Fpc_Model_Fpc_Front</amfpc>
            </request_processors>
        </cache> -->

2. 修改Mirasvi_kb.xml文件的 active的值为false

<config>
    <modules>
        <Mirasvit_Kb>
            <active>false</active>
            <codePool>local</codePool>
            <depends>
                <Mirasvit_MstCore/>
            </depends>
        </Mirasvit_Kb>
    </modules>
</config>
