From https://magentary.com/kb/cms-pages-transactional-emails-broken-after-supee-6788-patch/

The Update-SQL-Script had the wrong permission. Magento have to execute the script, with manual upload the script had the wrong permissions. now everything is fine.

Im not sure I understand the answer myself, but maybe someone else can help from here

I turned my cache off, and then was able to access. Then turn it back on. Like flushing it

Issue is after After update patch/Magento you need to do cache refresh and compilation disable.
