Error while loggin in and in admin panel (blank pages)
« on: May 02, 2007, 01:44:38 pm »

I've got a little problem. When user try to log in everything goes fine, but after clicking on "Log in" a blank page is displaying. When user type url of gallery in browser - works fine and he is logged.

The same is fith admin.php - when I do some changes in admin panel and click "save" - blank page appear (but changes are saved).

This blank pages really sux - for new users it can looks like site doesn't work at all, for me it's terrible too.

I did some modifications in code while install some mods or plugins. But when I restore ALL files form main directory and /include/ - nothing happens, still this ugly blank page is showing after logging in.

URL (don't laught, it's at develop stage ;-) ):

This is my login.php file (if it's important, if no please tell me what should I post here (since this blank page not only appear after loging in, as I explained above)) :

What is this doing at the top of the page?

Code: [Select]
<script language="javascript" type="text/javascript">
<!--
var win=null;
function NewWindow(mypage,myname,w,h,scroll,pos){
if(pos=="random"){LeftPosition=(screen.width)?Math.floor(Math.random()*(screen.width-w)):100;TopPosition=(screen.height)?Math.floor(Math.random()*((screen.height-h)-75)):100;}
if(pos=="center"){LeftPosition=(screen.width)?(screen.width-w)/2:100;TopPosition=(screen.height)?(screen.height-h)/2:100;}
else if((pos!="center" && pos!="random") || pos==null){LeftPosition=0;TopPosition=20}
settings='width='+w+',height='+h+',top='+TopPosition+',left='+LeftPosition+',scrollbars='+scroll+',location=no,directories=no,status=yes,menubar=no,toolbar=no,resizable=no';
win=window.open(mypage,myname,settings);}
// -->
</script>

Well.... calling of this script is in a classic-theme template file template.html by default :-)

Code: [Select]
<script type="text/javascript" src="scripts.js"></script>
<!-- $Id: template.html 2688 2005-12-04 03:22:35Z donnoman $ -->

I've removed this line anyway - no changes as you can see by logging in.

I don't understand. The code I posted is still there and I'm fairly sure it is the reason for the blank pages. Remove it.

My mistake - this script was included by tagblitz plugin. I've removed it - have no idea why it was there and what it was supposed to do.

But those blank pages still appear after logging in, take a look :-/

Looks like you have added some blank lines when you removed the javascript. Check any files you have modified or added for blank lines before the <?php at the start or after the ?> (if present) at the end.

Well...

There was no file with blank lines before <?php and almost all files (provided with plugins and cpg) had blank lines after last ?> tag. I remove these.

No changes. Anyway, if there would be a blank lines before <?php then a blank page wouldn't only appear when user try to log in - at least I think so.

So there are no changes. I really appreciate your help and still hope that you'll find out what the problem is :-)

I'm not sure what the problem is, I thought it was an issue with redirecting after login but it is something bigger than that. If you are happy to PM me FTP access to the gallery I can take a closer look.

UPDATE:

problem caused by a POTD (picture of the day/week) plugin.

It's important since this plugin requires one hack in functions.inc.php file and word is on the street that this hack is being considered for inclusion in the next  version of Coppermine (in fact, readme said that).

So meybe one of You (devs) would like to analise this problem in detail before decide to implement this one constantly.

Okay, the hack has nothing to do with these blank pages. It's a foult of this line in codebase.php:

Code: [Select]
$thisplugin->add_filter('page_html','potd_filter_page');
To bad, 'cause removing of this line make the plugin useless (we can't see "set as POD", etc in album menu under every file).
