well, it is somehow related, yes. in mamp everything works fine. but i just uploaded the files to the 1&1 server and:
-install.php works the first time, but shows me that folders have 705 and files have 604, and not 755 and 644
-install.php stops working after this! after refreshing or revisiting the page, i get
-the main navigation stops working and disappears
-i can log back in, but in settings, when i try to check whats wrong with the navigation by clicking the button "manage site navigation" i get the following error
i am using the lastest pulse and PHP 7.0. changing permissions with cayberduck/filezilla for all folders (755) and files (644) sadly does not change anything :-/ any ideas?
PS: i just changed everything to 777 right now again (folders and files), but still no luck, i still get both error messages...
