1. Installed the MC Template, did my customizations, and made it active.
2. Noticed while I was editing the template parameters that there is a newer version.
3. Clicked on the Button that says "Update" while still editing the template.
4. Was taken to the Joomla Extension Manager, which also notes that there is a new version.
5. Clicked on the Update (now from the Update Manager)
6. Got the error I first noted above.
I've used Admintools to make sure the permissions are OK, I've ensured that there's plenty of room on my hard drive.
Thanks for all your hard work and for giving us this patch. You saved my Royal Bazooka and 2 weeks of work. Thanks, thank you.... and if you forget, thank YOU!
