Re: White Screen O' Death
I found nothing in the error logs to suggest a memory problem, but I went and defined(‘WP_MEMORY_LIMIT’, ‘128M’); and things seem to be stable now.
I have added all the sites back and so far no white screens … which is great news.
Is it OK to leave the MEMORY_LIMIT at 128M? What is the recommended LIMIT for performance on a WPMU install with around 250 sites?
(and thanks for your help)
