This means you may have a empty line at the start of your file ie:

Code:
(blank line here)

&lt;?php

class Your_file_begins_here

Make sure the opening php tag is on line 1 of you file. You may also get this problem if you leave an empty line after a closing php tag. To save yourself some headaches, you may leave off the closing php tag for a file.

Thanks pickupman for the reply. I believe you were right and I have corrected this problem. In the meantime I have deleted the scaffolding code and inserted new code which doesn't use scaffolding, for working with my data base. The new code is $data['query'] = $this->db->get('entries'); With this code I get an error telling me that "entries' is a nonobject. It worked with scaffolding but not with the query code.

That's odd. That line should not throw that error. That would throw a database error for table not found. Could you post your code around that line?

The error is not because of that code(because the one you are whowing is correct)
the error is caused by a var $entries somwhere that has no data(maybe a spelling error somewhere

paste the code please ^^

How about your view? I am guessing that somewhere you have either $this->entries or $entries, however, $entries has not been set. Also, when posting code please use the code button in the menu above the message box.

I'm willing to bet that you're looking through $entries->result_array() or something in your view, when you actually want to be looping through $query->result_array(), or other such thing.

You haven't defined an object called 'entries' anywhere in the code you've shown us.

entries is the name of a table in my database. I assume that it is configured when the db class is called. I can insert and extract info from my "entries" table by using standard php queries. This is my view code:

Code:
&lt;html&gt;

&lt;head&gt;

&lt;title&gt;&lt;?php echo $title;?&gt;&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<h1>&lt;?php echo $heading;?&gt;</h1>

&lt;?php foreach($query->() as $row):?&gt;

<h3>&lt;?=$row->title?&gt;</h3>

<p>&lt;?=$row->body?&gt;</p>

<hr>

&lt;?php endforeach;?&gt;

&lt;/body&gt;

&lt;/html&gt;

There's your problem.

Code:
foreach($query->() as $row):

should be

Code:
foreach($query->result() as $row):
