till

Ok, I found the error.

Inside my plugin, I opened a connection. And when I closed it, it screwed up the rest of the site. So leaving it open fixed the situation for me. Not sure why though.

Ok, first of, thanks for your reply. 🙂

I’ll try to be more clear.

This is my filter:
function my_filter($string_text)
{
$post_id = $GLOBALS['wp_query']->post->ID;
if (empty($post_id))
{
return $string_text;
}
/*
query database and check if extra information
applies to this post.
*/
$query = "...";
...
if (mysql_num_rows($res) == 0)
{
return $string_text;
}
$infoObj = mysql_fetch_object($res);
$string_text.= sprintf(
'<ul><li>%s</li></ul>',
$infoObj->foo
);
return $string_text;
}

So this is what I do.

Checking the source, I see no HTML or PHP errors. For example, once I activate the filter, the categories are gone missing. But there is no error, it just says “>> No categories” in place where the list should be.

Any idea?

WordPress 1.2.2 🙁

So I guess I need to update as soon as it comes out, right?

No, it’s more or less a sign of ineffecient database queries, variable use and so on. The server should be really fine.

I am not going to increase the value because a script tries to consume more than it is supposed to. 🙁
