Blank page after installing 5994 patch

[lucia2222]

I have just done the security patch updates on a magento 1.6.0 site. They all seemed to install ok by SSH. Before installation I turned off compiler and created a Router directory. then once installed site seemed ok, went into admin to clear the cache's I did flush mangento cache and also checked all the cache's in the list and did a refresh, at this point my admin and site went blank, nothing in the pages at all. Help!

Have you cleared your cache?

There could be several reasons for this, 1. Make sure the Magento and patch version you have installed. 2. Did you make sure about the compiler disabled before patch installation?

I installed patch supee 5994 on magento 1.7.0.2 , flushed the cash, ran compilation and enabled de compiler, this results in a blank admin page.

When I turn of the compiler the Admin page is visible.

Anybody an idea?
