Hello,i had the same error report.For me what fixed it was to remove this part of the code:
function WebLoginPE($LanguageArray, $dateFormat = '%A %B %d, %Y at %I:%M %p', $UserImageSettings = '105000,100,100', $type = 'simple')
{
$this->__construct($LanguageArray, $dateFormat, $UserImageSettings, $type);
}
in webloginpe.class.php, located around lines 163-166.
Apparently,these lines were used for PHP4 compatibility. If your server runs on PHP4 however,these lines of code might be needed, so i suggest trying other solutions first.
