Not able to populate dummy data in phosphorum/phalcon forum initial install

Installed phosphorum(phalcon forum) successfully on my WHM server(shared hosting). But when populating database using command usr/bin/php /home/xxxx/public_html/forum/forum seeder:populate , I am getting this message in command prompt(using putty SSH)

Start X-Powered-By: PHP/5.6.31 Content-type: text/html; charset=UTF-8

But no entries in database. When i check app/logs/application.log, it says,

[04-Aug-2017 17:53:34][DEBUG] [boot] Parsed options:
[“seeder:populate”] [04-Aug-2017 17:53:34][DEBUG] [boot] Task
definition: {“task”:”seeder”,”action”:”populate”,”params”:[]}
[04-Aug-2017 17:53:34][ERROR] WhoopsExceptionErrorException:
fwrite() expects parameter 1 to be resource, string given in file

on line 28 Stack trace:

/home/xxxxx/public_html/forum/forum:28 fwrite()

I googled, did not get any solution. Tried different ways to my knowledge without success. Did anyone get this kind of error while installing? if so, any solutions?Is there any manual way/.sql to populate data?
Phosphorum Version 3.2.1
