Our older plugin also only supported PHP 5, unfortunately. But I ported it over the holiday and we’ll be formally testing it in PHP4 this week.

Hey, so sorry guys! This is Matt from AddThis. We wrote this for PHP 5 only, not PHP 4. However, it seems like despite the official end-of-lifing last year, it’s still one of the most dominant flavors, so we’re going to make a backport soon. Sorry for the trouble!

Best,
Matt
