Fix for 2.5 is here: https://open.vanillaforums.com/discussion/comment/251817/#Comment_251817
Thanks to @Caylus
@x00, could you please upload the following fix? (See attachment)
I've included a JSON file to make it compatible with 2.5, included the fix described in the topic linked above, and changed "$this->PluginInfo['Version']" to "$this->getAddon()->getVersion()", because that threw some warnings too.
