I encountered an issue that seems that should be fixed since i saw it appear in JIRA a couple of times before.

When installing a fresh Jenkins LTS 1.480.3 release on Windows Server 2008 R2 x64 I can't find any plugins in "Available" and "Updates" tabs.

I receive the following error:
Apr 19, 2013 1:34:59 AM hudson.model.UpdateSite doPostBack
SEVERE: <div class=error><img src='/static/9545af49/images/none.gif' height=16 width=1>Digest mismatch: 1Woxyt3oLgioZax7SGlbwYITc98= vs +JLZbigPye2eA9Fsv6sa3DW3q2s= in update center 'default'</div>

I have tried the latest Jenkins version and I don't receive this issue. The thing is - i want to go with the LTS version since i'm installing it on a PROD environment.
