dreamhost VPS returns a lot of blank pages After upgraded from shared hosting to VPS (for more memory), my site returns a lot of blank pages, for example:


plain /update.php is OK, but returns blank page after clicking Continue and Update
plain /admin/reports/status is ok, but /admin/reports/updates/check?destination=admin%2Freports%2Fstatus returns blank space


php memory_limit is now 512M.

Any dreamhost user shares some experience?
I would check PHP error reporting on the server : usually, WSOD are caused by hidden PHP errors. A value of E_ALL &amp; ~E_NOTICE is usually fine, at least for development.
