Why don't just use Custom html/text widget. It's available on all these pages. 

because thats not possible , i want put code in special place where that's not possible to do it via widget

What are these places? Provide screenshots, please

between welcome and newsfeed

between avatar and profiledetails

widgets are not perfect to do anything

also widget is not available for main page

I need to make some tables manually and move codes to places i would like

I'm sorry but this is exactly where the Custom html widget comes in handy, otherwise you can't do it. 

What are you trying to achieve? Do you have difficulties with the code or something else?

why i cant find that page files ?!

widget limited me coz there is just two columns but i want three columns

also Main page isnt available for change in cpanel

Because there's no such pages, they are dynamic, all parts of the page come from the different parts of the code or database. 

So can you please tell me where i can find this code (Its on main page already)

I need to copy it and paste it in another pages

The code of the customize this page button or what?

i want find 'social services' codes on this page

Billy, can you please be persistent, first you say you want to insert something in three columns, now it's social services? Please elaborate what you're trying to achieve in more details so we could assist you more effectively. 

Both

I want find that code and change location

So for first if u tell me that code is located in what file i'll be appreciate

The code is in the ow_plugins/social_sharing/activate.php file

I added that php code to custom html widget , but didnt works .

How add this plugin to a custom widget ?

This is a custom code modification. 

I want add php code to place showed in the image , what file i look in

(widget cant add php)

Billy first of all, one request per topic. 

you have to do that in these two files: 

ow_plugins/contact_importer/components/widget.php

ow_plugins/contact_importer/views/components/widget.html

Hi Ross

I was mean under 'contact importer'

i want make a php box there

You need to create a plugin in order to do that.
