I checked those files, and there aren't white spaces, these are the ends:

common.php:
} elseif($xoopsUser) {
$xoopsUserIsAdmin = $xoopsUser->isAdmin(1);
}
}
?>

functions.php:
function xoops_trim($text)
{
if (function_exists('xoops_language_trim')) {
return xoops_language_trim($text);
}
return trim($text);
}
?>

As I copied this file from a stable installation, I think the files are not the problem. Thanks again.

Hello,

I had a stable XOOPS installation (2.0.13 spanish), but I needed to change the directory, prefix and database. I copied all files to the new directory, I put the right permissions to cache,templates_c and upload directories.I copied the old tables with a new prefix in the new database, and the I changed mainfile.php with the new values.

Now, the site seems to work fine, but it spends much time to load. I activated php debug, and the errors are:

Notice [PHP]: Constant XOOPS_SIDEBLOCK_LEFT already defined in file include/common.php line 44

I think the important problems are session problem and constant problems. I deactivated all cache options in preferences, but the problems continue.

Thanks beforehand.

Hello,

I have activated the php debugger, and I obtain hundreds of messages, by example:

Notice [PHP]: Only variable references should be returned by reference in file include/functions.php line 493
Notice [PHP]: Only variable references should be returned by reference in file include/functions.php line 493
Notice [PHP]: Only variables should be assigned by reference in file class/database/mysqldatabase.php line 236
Notice [PHP]: Only variable references should be returned by reference in file class/database/mysqldatabase.php line 383

The displayed files are many, the directories are: class, include, kernel...

The XOOPS version is 2.0.13 in spanish language. When these messages are displayed at begin of page, XOOPS works fine except the fonts are bigger. If the messages only are displayed below page the fonts are ok.

Can anyone helps me?

Thanks,
