<p>When migrating from 1.5 to Joomla 1.7 you might have issues while saving the new article with Invalid parent id error message.</p>
<p>When you try to save the new article you might receive the following message:</p>
<p><img class=" size-full wp-image-275" src="http://wincert.net/wp-content/uploads/2011/08/parentid_error.PNG" alt="" width="317" height="39" border="0" /></p>
<p><strong>Save failed with the following error: Invalid parent id.</strong></p>
<p>No matter for the error message, article will be saved but won&#8217;t get the asset_id.</p>
<p>I&#8217;m not sure if this is related with something gone wrong with the migration, but here&#8217;s how to fix this error:</p>
<p>Login to Joomla Administrator | Select <strong>Menus</strong> &#8211;>; <strong>Menu Manager</strong> | Click on the Check All box and click <strong>Rebuild</strong></p>
<p>Now select <strong>Content</strong> &#8211;>; <strong>Category Manager</strong> | Click on the Check All box and click <strong>Rebuild</strong></p>
<p>Open <strong>Content &#8211;>; Category Manager</strong> and click on the each top category to open it and then just Save it.</p>
<p>After you&#8217;re done with the top categories, open sub categories and save them all one by one</p>
<p>Error message should be gone now when saving new articles.</p>

<p>You should also open article/s that were saved with this error message and save it again.</p>
