Wp-cache blank page issue with PHP 5.1.6
Since the upgrade from PHP 5.0.4 to PHP 5.1.6, the wp-cache plugin in wordpress failed on any pages that were not cached before. The page shows blank screen on the first run - it works after it cached once on the page. I did some quick searches and found this solution for wp-cache version 2.0.19 with php 5.1.X.
Out of my curiosity, I searched for this behavior changes from PHP 5.0 to 5.1 and found this bug report.
