I've just upgraded out test-instance of Confluence to the ver. 4.2.5. The main reason for the upgrade were several bugs in Plugins: Excel and Jira.
After the Upgrade I've noticed, that Confluence won't work with IE9, so I've switched my browser to IE8 mode and Excel-plugin is working again. Plugin for Jira still does not work.
I've already read here that Confluence 4.2.4 won't work properly in IE9 and I suppose that's the same with 4.2.5.
Has anyone else had such problems? Maybe there's a workaround there to get Jira plugin working...
