I'm currently trying to slowly update our very outdated CMS made simple installation. But have run into an issue updating from 1.11.4 to 1.11.6. Meaning that I am unable to create or edit pages. When I try to edit or create a page it shows a menu without styling with links to the pages on my site.
This is what shows when trying to edit or create a page.
Has any one got an idea how I solve this. I am trying to solve any issues that appear before updating to the next version so it is easier to see when it appears.
