Why am I not able to install the Page Approval macro?

[Adam Henry]

Every time I try to install the Page Approval macro, I receive an error message that states the following: 

An error occurred during installation. Refer to the logs for more information.

Naturally, I go check the logs and this is what it states (where xxxxx = our domain):

I've Google'd this issue but to no avail. 

We are using Confluence 5.7.1. We were, however, able to install this on a replica of our site and it worked just fine. 

Thanks in advance.

It was not compatible with confluence 5.7 it is now with the release of the 2.2.5 version. Maby you should try again!
