I have just setup my first completed SS on Webdrive NZ and begun testing the system. All seems well on the surface.
FYI - there are two must haves at the top of the htaccess file for this host:
php_value memory_limit 64M
php_value allow_call_time_pass_reference 1
You will intermittingly get memory exhausted errors without the first one, as Webdrive's default memory_limit is 20MB. This will always happen when you do a ?flush=1 or db/build/?flush=1 if you don't add it.
The one (and so far only) problem I am having is when trying to save a page in the CMS. It doesn't matter what page type I try (including the default Page), I get "Error saving content" in the lower left of the content window, and this error in Firebug:
POST http://www.domain.com/admin/?executeForm=EditForm 500 (1868ms)
Safe mode is turned off, and this is all working fine on local WAMP, so must be a configuration on the live server (I don't have access to raw logs).
