New Post: New line at the beginning

Hello!

I managed, to remove the blank line, by editing the template, and removing these lines from document.xml:

<w:p w:rsidP="00ED3C6C" w:rsidRDefault="00ED3C6C" w:rsidRPr="00ED3C6C" w:rsidR="00ED3C6C">
        <w:bookmarkStart w:name="_GoBack" w:id="0"/>
        <w:bookmarkEnd w:id="0"/>
</w:p>

But now, OpenOffice won't open the file. I'm using this html:

<table border="1">
  <tbody>
    <tr>
      <td>asd</td>
      <td>asd</td>
    </tr>
    <tr>
      <td>asd</td>
      <td>asd</td>
    </tr>
  </tbody>
</table>

Do you know what can be the problem, with OpenOffice?
