I tried to upgrade from version 1.1.10 to 1.1.11 on my computer (http://localhost/...). You have a "Whoops, looks like something went wrong." Error message. How can I solve it? Is there another way to update other than "../install/updates" ??
You can try enabling debug to see more detailed error, here how to: https://akaunting.com/docs/developer-manual/debug
