I have just downloaded and installed ms_files-7.x-2.13.tar
Fatal error occurs when activating module.
Fatal error: Function name must be a string in /home/xxxx/public_html/xxxx/sites/all/modules/ms_files/ms_files.install on line 40
Update:
The issue appears to have been resolved by creating a private files folder and updating the location in Configuration->Media->File System->Private file system path








Thanks for letting me know. I have changed the $t to a regular t() which should fix the fatal error.
This code only runs if there is no private files directory.
Sincerely,
Leighton Whiting
