Hello 

Error 1: Looks like some module was installed incorrectly or has some bug. Try to uninstall newly installed modules. It will help you to find out the module which causing the error.

Error 2: Photos module tries to add items in "My Profile" and "Profile View" top menu items. If you deactivated them via admin panel -> builders -> navigation menu then Photos module cannot do the operation correctly. You need to activate the default items or modify installtion script of Photos module.

how can i return the menu to the default of dolphin ?
