Hi,

I'm running Drupal 4.7.2 and was working with CCK when things suddenly stopped working. I realize that CCK (and views, which I was also using) are not yet core, but at the time this error began I was simply adding and editing nodes, so I really don't know where this thing came from.

Anyway, when I try to execute any page (basically anything in which I click a button) I get a blank page. If I reload the page or hit enter in the address bar, the action is executed but I get errors popping up, specifically the "cannot modify header information" error, which from prior experience I know probably is indicative of some other unknown error.

So then I made the big mistake, which was that I thought if I logged in as user #1 I could troubleshoot things more exactly ... silly me, I can't log in because, of course, the form isn't being executed.

Since I can't log in there's not a lot I can do. But looking at the watchdog table in the database I'm getting the following entries each time I try to log in:

Session opened for <em>[user1]</em>. [that's good!]

session_regenerate_id(): Cannot send session cookie - headers already sent by (output started at /var/www/[mypath]/themes/[mytheme]/template.php:50) in /var/www/[mypath]/modules/user.module on line 943. [not so good]

Cannot modify header information - headers already sent by (output started at /var/www/darfurscores/themes/[mytheme]/template.php:50) in /var/www/[mypath]/includes/common.inc on line 266.

Line 943 in the user.module is, as it specifies, session_regenerate_id, which I gather tries to set the cookie that marks me as logged in. Line 266 in common.inc is in the drupal_goto function, where it tries to invoke the header.

If anyone has any ideas at this point, I would love to hear them. Some specific things that would be helpful for me to gather more information:

- Anyone have any ideas how I could log in or set that cookie without going through that form?

- Anyone know what row in which table controls what theme is set? Since I'm using a custom theme, and the problem could be in the template, switching to another theme might solve it or at least allow me to investigate.

- Is there anywhere else I could look for besides watchdog to figure out what the errors are?

- Are there any good database analysis/repair tools, in case it's some kind of corrupted database entry?

- I tried turning off all modules (everything except the required ones, even core) and that didn't fix it. I turned them all back on before I tried switching users, so I could turn them all back off directly in the database if that would be a good idea. Should I try removing the non-core module tables in the database completely? Is there a list somewhere of the tables and rows that CCK and views (though I think if there were a problem it would be CCK) create/affect? Some are obvious, but I imagine they create entries in various tables that I might not think to look in...

Any help would be greatly appreciated, as right now I have a very pretty, very nonfunctioning site...

Do you have a ?> and/or whitespace after it in your
template.php? Look 
at line 50 in your template.php and see what's there. This
is the most 
likely place to look for your problem.

    Maybe I'm missing 
something but is there a resource somewhere that ties together example with 
Modules?

 


For example: When I 
visit http://drupal.org/project/acidfree it 
would be very helpful for someone considering the use of the module if there 
were a library of links to some sites that exhibit the module in 
action.

That was exactly it. Thanks!
 

For future reference, though, does anyone know how to switch the theme by changing some setting in one of the tables?
