Unable to install plugins
Asked by Christian Barsch:

Hello,

I've upgraded our Confluence instance to v5.1.1. Now we are unable to use/install plugins. The error is described in the [documentation](https://confluence.atlassian.com/display/CONFKB/Universal+Plugin+Manager+is+Inaccessible+or+Does+Not+Show+Any+Plugins). But when we try to upload a plugin on http://\<server base url\>/admin/viewplugins.action the following error occurs:

```

body: Hello William,

Thank you for the help.

I've already done this step. It's in the documentation too, but it didn't helped us. The plugin (Gilffy) seems to be outdated. The new Gliffy version is working now.

Kind Regards,

Anon


author: William Zanchet [Atlassian]
body: Hello Anon,  

Since you did an upgrade recently, I would suggest you to rebuild our bundled plugins, that way Confluence can build them back, having the 'compatible' version. To perform that could you please follow the step below?  

\* Shutdown Confluence  
Delete the content from the following folders:  
\* \<confluence-home\>/plugin-cache  
\* \<confluence-home\>/plugins-osgi-cache  
\* \<confluence-home\>/plugins-temp  
\* \<confluence-home\>/bundled-plugins  
\* \<confluence-home\>/bundled-plugins_language  
\* Startup Confluence  

*I highly suggest that you schedule a downtime to perform it, because we don't want to disturb your business.*

I hope this helps.  
Cheers,  

WZ
