With my blog still running on Mura 5.5, I figured it was about time that I upgraded to 5.6. I logged into the admin and ran the update, only to find that Hostek caps the execution time on scripts. This is usually a good thing, but in this case my upgrade got cut off midway through. I was no longer able to access the admin and reloading Mura via the URL didn't help. I spoke to Hostek support, who increased the execution limit for the upgrade script, but I was still at a loss as to how I was going to run it! Anyway, if you find yourself in a similar situation, you can hit the upgrade script directly by accessing it at /admin/index.cfm?fuseaction=cSettings.list&action=updateCore (duh). Hopefully this will help some poor, lost soul with a broken Mura upgrade.
