Somehow I broke my JDownloader installation, I think by meddling with the network settings. Nothing would download, and the auto-update was borked. I decided to delete it and reinstall it, but I had quite a lot of download packages queued, and wanted to rescue them. I managed to do this successfully, here’s how:

Locate the “backup” folder, in JDownloader’s root directory. For me, as I used this method to install JDownloader, the folder was in “/opt/JDownloader/”. Find the most recent “backup.zip” file. Note that there may be some numbers between “backup” and “.zip”. In Ubuntu’s default file manager, Nautilus, one can select “List View” and then click “Date Modified” to easily find the most recent file.

Copy this file and paste it to your desktop.

Create a new folder on your Desktop, call it “BACKUP”. Copy all files in JDownloader’s root directory into this folder.

Follow these instructions to install JDownloader. You can skip the “sudo mkdir /opt/JDownloader” step if you installed JDownloader with this method.

When JDownloader is installed, extract the “backup.zip” file you copied to your Desktop and modify then execute the following in a terminal:

sudo mv ~/Desktop/database.script /opt/JDownloader/config/database.script
sudo mv ~/Desktop/database.properties /opt/JDownloader/config/database.properties

Open JDownloader.

Your packages should have been restored. If you’re happy with the new installation, you can go ahead and delete the “BACKUP” folder.

Yesterday I was trying to implement a Shadowbox contact form in the Bay of Islands SPCA site, but I just couldn’t get it to work. I was using the standard setup that works perfectly well on the Te Kuiti SPCA Site:

<script type="text/javascript" src="http://tekuitispca.org/sb/jquery-1.2.3.min.js"></script>
<script type="text/javascript" src="http://tekuitispca.org/sb/shadowbox-jquery.js"></script>
<script type="text/javascript" src="http://tekuitispca.org/sb/shadowbox.js"></script>
<script type="text/javascript">
 
Shadowbox.loadSkin('classic', 'http://tekuitispca.org/sb/skin');
Shadowbox.loadLanguage('en', 'http://tekuitispca.org/sb/lang');
Shadowbox.loadPlayer(['iframe'], 'http://tekuitispca.org/sb/player');
 
window.onload = function(){
 
    var options = {
        initialWidth:     '0',
        initialHeight:    '0'
    };
 
    Shadowbox.init(options);
    }
 
</script>

And the HTML:

<a href="http://www.tekuitivets.co.nz/" rel="shadowbox;initialHeight=0;initialWidth=0;width=900;height=700;" title="Atkinson &amp; Associates Vet Clinic">Atkinson &amp Associates Vet Clinic</a>

I uploaded all the files, changed the addresses in the above code. Strangely, it worked find in Rapid Weaver, but not in Safari, Firefox, Epiphany or any other browser – either in export mode or after a full upload. My search for “Shadowbox just won’t work!” yielded no results, so was forced to use the programmer’s final weapon – exhaustive trial and error.

I tried various things for about an hour, and finally struck gold with this:

<script type="text/javascript" src="http://boispca.org/sb/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="http://boispca.org/sb/shadowbox-jquery.js"></script>
<script type="text/javascript" src="http://boispca.org/sb/shadowbox.js"></script>
<script type="text/javascript">
 
	Shadowbox.loadSkin('classic', 'http://boispca.org/sb/skin');
	Shadowbox.loadLanguage('en', 'http://boispca.org/sb/lang');
	Shadowbox.loadPlayer(['iframe'], 'http://boispca.org/sb/player');
 
	jQuery(document).ready(function(){
 
		var options = {
		initialWidth:     '0',
		initialHeight:    '0'
		};
 
		Shadowbox.init(options);
 
		jQuery("#contact-us").click(function(){
			Shadowbox.open({
			        player:     'iframe',
			        title:      'Contact Us',
			        content:    'http://boispca.org/contact/',
			        height:     500,
			        width:      400
			    });
		    return false;
		});
	});
 
</script>

And HTML:

<a href="http://boispca.org/contact/" id="contact-us" title="Contact" >Contact</a>

Now whenever one clicks the contact button, Shadowbox is called through jQuery.

I don’t know why the normal way didn’t work!

I joined Twitter yesterday, and installed the Twitter Tools plugin.

Unfortunately, the “Post from sidebar” feature was broken for me. I think this was because my Wordpress installation is in a different directory from the actual blog, and Twitter Tools was looking in the wrong place for class-snoopy.php.

To fix it, I had to edit one line in the “do_tweet($tweet = ”)” function of the twitter-tools.php file.

I changed the 7th line of this function to:

require_once('/home/a_folder/public_html/wordpress/wp-includes/class-snoopy.php');

Fixed!

If you experience this problem, replace “/home/a_folder/public_html/wordpress/wp-includes/” with the path to your Wordpress installation’s class-snoopy.php file.
