Error: could not save password - 'unable to update file 'settings.pl.exclusive_lock_request' - Permission denied'
If you encounter this error during initial setup, then the problem is most likely that the "searchdata" folder is not writable. You will have to set or reset permissions.
For new installs, the "save password" action is the first action that tries to write to the folder, and so this error will always arise when the folder is not writable. This problem occurs often on Windows-based web servers because it is not easy to remotely set permissions. This is the problem in 99% of the cases.
In the remaining 1% of the cases, there is already a file named "settings.pl.exclusive_lock_request" in the "searchdata" folder, and it needs to be deleted.
