Anything in your PHP Error Log?

No errors. (Only from my Wordpress install which is gone.) So I reset the log, did a new post with a link to be processed and no errors in the log still.

Anything else to check?

To reconfirm, you're saying this positively works on the latest 4.2.3 version? Are you running this there?

Also can you confirm that the current ZIP version is all I need or are we talking about modifying it based on the comments since the ZIP?

I'm not saying any of that, I simply asked if there was anything in the error log. What version of PHP are you using?

I'm on PowWeb: Current Default version of PHP: 5.6

It's still working for me on vB 4.2.3 with PHP 5.5.34

As far as I know, vB4 isn't certified above PHP 5.5.x yet, is it?

My PowWeb panel lets me pick my PHP version: 5.3, 5.5, or 5.6. Should I bump it down to 5.5 and report back?

THe minimum requirements for vB 4.2.3 are:

vBulletin 4.2.3 requires PHP 5.4.0+ and MySQL 4.1.0+.

As far as I know, you should be fine with PHP 5.6.x and vB 4.2.3. :)

Given this was written for vB3.7 (and probably PHP 5.2 or even 5.1) its not going to be much of a surprise if it doesnt work properly on 4.2.3 and PHP 5.5 or 5.6.

Look if you have fopen enabled in php config, it's needed in this addon.

THANK YOU, Rhodium! It did not matter which PHP version I used, all worked once I set allow_url_fopen = On
