TOPIC: Configuration tab not showing after upgrade to 2.7.12e

I am running Dt Register on a live site for a client and have begun the upgrade process to 2.7.12 from 2.6.4, having today purchased the latest version.

I run all upgrades on a local copy first, to smooth out any bugs before going live. I have successfully upgraded the local and live site to 2.6.9c.

However the installation of 2.7.12e on the local site has run into a problem. The migration of data was fine, and I can open all tabs except the configuration screen which won't load.

Reading through this forum it seems this is a known bug - with jce content editor? I have turned off jce; tried reinstalling etc - but am now completely stuck and obviously can't load it on the live site.

There is no conflict with JCE. Please submit a ticket with admin access so we can check this out for you.
