Based on https://marketplace.atlassian.com/plugins/com.zagile.jira.plugin.zteamworkjira/version/4341, looks like the plugin is only compatible until Confluence 4.2.7. If you want to know more if the plugin will be compatible with Confluence 4.2.8, you can directly contact the plugin developer at info@zAgile.com since this is a third-party plugin which is not developed by Atlassian. Hope that clarifies.
I know I'm being obstinate here, but you're asking us for help and giving us a name which you're then expecting us to make the effort to search for.
That is not helpful. At least link to the plugin. If you can't be bothered to make it easy for us to understand what you are talking about, then many of us won't be bothered to look it up and read it. A simple link is enough.
p.s. For plugins, you're better off asking the vendor than the community here - we don't know what the vendor is doing with it.
