Unfortunately the panel doesn’t seem to be working correctly on my site. I managed to login but there are a number of blank screens when I try to action certain things. For example: logging out, site options, account edit.
I also tried downloading the site to work on it locally and the panel appears as a blank page. All pages are working correctly on the site. Any other information I can get please let me know.
Mamp usually works with Kirby 2 out of the box, without any additional requirements (at least, if you are running an up-to-date version of Mamp). Have you made sure to clear your browser cache, remove any sessions in your browser and then log in again?
