I changed to mantra. Since then I can not clickto >> Design >>> Themes in the Backoffice.
After then I disabled all plugins. Same Problem. If i try to click “Themes” then show me a white Page with Error message “Critical Problem bla bla….
Mantra has been problematic since the update. I can not do anything right now, because I can not change the theme. does anyone know the problem? Think about if I changed my themes. Have more often problems with Cryout Themes in the past. Such things just not happen.
