I suspected file permissions. My hosting is Windows/IIS, and I need to grant write permissions where required– where is it required?
I tested by changing wp-content and all below to 777 for the IIS user, then trying the Install BuddyPress/continue -> and I got the “Installing Plugins…” on the second attempt (the first one timed out). You should document your file permission requirements.
Now Activating Plugins… next error, suggestions?
