@Thulani I have Moodle installed in the LAMP app; it looks like something like OrangeHRM, and even Sentrifugo, is also installable via the LAMP app. I'll give them a whirl and see if they are.

(some time later...) Ok, both Sentrifugo and OrangeHRM installed fine; there was a bit of a trial and error setting up email correctly with Sentrifugo but it worked out. Sentrifugo is running well now on the LAMP app with just 256MB ram; OrangeHRm keeps giving me weird SQL errors when adding (but failing) new employees (SQLSTATE[22007]: Invalid datetime format: 1292 Incorrect datetime value: '2020-06-13 09:53:34pm' for column 'created_date' at row 1) and other error messages.
