Error after installing a product.

[jango49]

Hello everybody.

I use vbulletin 4.2.5

every time , after I import a product , I get a browser error message like this :

Content Encoding Error

The page you are trying to view cannot be shown because it uses an invalid or unsupported form of compression.

Please contact the website owners to inform them of this problem.

however, it seems like the product was successfully installed....

any suggestions why and how to fix this ?

THANK YOU in advance,
Jango

Disable gzip compression in the admincp, then empty vb's cache in maintenance, try importing another product to test if the error is gone.
