I tried to upgrade my Confluence instance from 5.1.3 to 5.3.4 using the upgrade option available while installing Confluence. On startup, the application is not able to render any macros. The following is the error I get:
caused by: java.lang.IllegalStateException: Cannot retrieve plugin module before it is enabled: PluginModuleHolder[(unknown; not enabled)]
Also, the macro browser doesn't pop up on click.
