Redmine

A few weeks ago I upgraded to 1.3.0 and all code blocks now displayed incorrectly :(

Example code:

<pre><code class="html">
        <if test="authorcfields:|:$author['custom_fields'] != """>
            <foreach loop="customFieldsOuter:$author['custom_fields'] as $group => $data">
                <foreach loop="customFields:$author['custom_fields'][ $group ] as $field">
                    <if test="$field != ''">
                        <li>
                            {$field}
                        </li>
                    </if>
                </foreach>
            </foreach>
        </if>
</code>

Invalid result:

        <if test="authorcfields:|:$author['custom_fields'] != """>
            <foreach loop="customFieldsOuter:$author['custom_fields'] as $group => $data">
                <foreach loop="customFields:$author['custom_fields'][ $group ] as $field">
                    <if test="$field != ''">
                        <li>
                            {$field}
                        </li>
                    </if>
                </foreach>
            </foreach>
        </if>

How I can remove these unnecessary icons without editing wiki pages? Thanks!
