Something goes wrong
I recently Installed the mmm-moon-phases module and since then whenever I reload/restart mirror something weird happens. All modules are loading in the first page (MMM-pages). If I go to page 2(MMM-Page-Indicator) and back all modules are arranged as they should be. Untill the next reload/restart. When I disable the module in my config.js mirror reloads perfectly. Any Ideas?
