Error database appears to need patching to a higher level; how do I rerun db upgrade?

That you have gotten as far as you have I would say that there is nothing wrong at this point with the way you have upgraded (zc_install process). The fact that in your summary you didn't indicate experiencing errors while installing the responsive template supports Dr. Byte's statement that the package was missing some installation "code". I thought that the template install package was complete, just. From past experience of the author.

Thank you for summarizing this thread and setting me straight. Keep on with the good work. I would suggest though with specific problems related to a plugin that has a support forum, that you go visit it, read through the forum to see what other issues have been identified and see what resolution has been offered. More than likely someone else has had the problem, but if the issue is not identified, try to provide as much information about reproducing the issue as you can and hhopefully someone will be able to help. Again keep it up, seems like things are going well.
