Sorting alphabetically in the membership choices, DOES NOT work!
If you go to membership and click on edit membership there is now a choice for your links and messages where you can check off as your permanent default alphabetically. Sort and View Preferences. Then you click on save. When you click on save in some groups it says the usual "Sorry, an error occurred while loading the content." In some groups that choice does save, but does not place the links and folders in alphabetical order. Some lists are lucky and their choices are saved and the contents in both the files and links sorts alphabetically and stays that way. Please fix. As for that "Sorry, an error occurred while loading the content," it keeps happening when trying to sign into a list, open up a link or file, read a message etc..
I just did the first two lines of this post...and it worked for me. I tried it on three groups.
