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.

Check for white space at the end of common.php and functions.php

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.
