Our site coded in Php smarty automatically logs out a frontend user after, say, 30 minutes of inactivity. Previously this did not happen. Subsequently, like most sites, we wanted to cause users to be logged out from prolonged periods of inactivity. We now want to Undo this.
Keep the original file before you make any change.
Once you detected and make changes, re-test to confirm.
Then attach and send me the files before and after the changes to me for consideration, and let me know in which subfolder they lie.
