Blogs will not install upon creation.

When users try to create a blog, a number of those created (and now, almost all of them) are not created, and instead, we receive the following error: "The blog you have requested is not installed properly. Please contact the system administrator."

We have looked through a multitude of tickets and forum topics on the subject, but we have not located an answer to this problem. Earlier today, I defaulted the config’s Default Charset option from utf8 to an empty string, per the random advice from forum topics, and it seems like we’ve not had any luck so far. This issue has been going on for months. We’ve been able to avoid the issue slowly as the site grew by disabling some of the bulkier plugins from the WPMU site (Firestats and Sociable among them). But now, with over 1,000 registered blogs, the problem has become nigh unavoidable.

Has anyone been able to discover the root of this problem, and if so, how have they fixed it? I know a bunch of WPMU admins simply delete broken blogs and create new ones for the users, and this was our solution for those sporadic cases in April and earlier this month, but now it seems almost every blog fails upon creation. To top it off, we can’t use the admin Add Blog feature anymore – the page halts during execution, throws back an error, and the blog is half-created just like the blogs that users attempt to create (to specify, records exist, but the blogs do not load, and users are not linked to those blogs). The other popular solution is to completely reinstall the platform, which we will do in time, but I don’t want to find that the problem recurs after 500 blogs on a newer installation.

Our website is

We use WordPress MU 2.6. We do not use multi-DB or any scaling solution, and we do not use BuddyPress. We do, however, have plans to recreate the WordPress install using WPMU for WP 2.8 with the 256 table Multi-DB solution and BuddyPress (should Multi-DB and BuddyPress be able to coexist).
