checkdnsrr() PHP always return true or false, alternative with Windows

Have you had problem with the PHP function checkdnsrr() is always returning false?
Then you should first check if your php-version is >= 5.3.0 otherwise it wont function in Windows environment.

Have you had problems with checkdnsrr() is always returning true?
Then there may be other problems with windows not able to do the DNS-record check properly.

An alternative to checkdnsrr() with Windows built in function, "nslookup" and by wiriting this much self-explaining php-code:

    if(!empty($host)) {
        $recType="ns";
        exec("nslookup -type=$recType $host",$output);
        foreach($output as $line) {
            if(preg_match("/^$host/", $line)) {
                return true;
            }
        }
        return false;
    }
    return false;

Good luck!

Image slider, vSlider to Wordpress not function in IE or Chrome

Are you having problems with the image slider plugin vSlider 4.0 or another Wordpress image slider plugin? The problem I'll describe here is that the images won't be shown / displayed in Internet Explorer and Chrome but works fine in FireFox.

Then the problem can be that the plugin is configured with an "auto resize" setting. Try with unset this and see if the problem disappear.

Hope that will help you out here.
