Hi

I recently upgraded to 5.6.1. Ever since there has been a weird error coming. When i access the site using IE 8 / IE 9 the site throws up an error. However, the same when accessed via Chrome opens correctly. The error show some sort of compression error. When i change the Compression Setting to "No Compression", the error doesn't show in IE (obviously the site renders slowly).

The error log is below:

I am using Gzip compression and my hosting environment is W2K8 with SQL Server 2008. Can someone suggest where should i be looking to correct this error?

Thanks
