Joomla 3.7 Change Default Registration Link ID

Right now I'm testing a site on local host. But to show the error I'm running into, go to this address:
http://www.bearvalleycomp.com/cust/twoil/index.php/component/users/?view=registration&Itemid=101
What I want it to do is show the page like this:
Edit: I don't have enough rep to post more than 2 links...Enter that same link above without the "&Itemid=101"
But I'm lost in the code to find the address to remove the Itemid=101
I have found a guide where I can edit it through the system menu as shown here:
https://www.templatemonster.com/help/joomla-3-x-edit-registration-page.html#gref
But it appears this 3.x might not be updated for the latest edition.
Any insight would be appreciated. Thank you
After looking through multiple files, I did find the answer to change the link. It's located under /modules/mod_login/tmpl/default.php. Down around line 101, I was able to add &Itemid=114 to the end of the index.php?option=com_users&view=registration making it look like this:
index.php?option=com_users&view=registration&Itemid=114
Now when I click on Create an account, I see a page for only registering an account.
However, now I get mail errors but I can look into that later I guess.
To work around this problem you have to add the register page to a hidden menu (normal menu, but willout position module) and use that alias item on your link.
This way you can decide which modules to show or not for that particular page.

Codeigniter don't load changes made in the source code

I created an online inventory system with a downloaded template. At first, I can see all my codes is being reflected in the view page but after some time no matter what I added or change in my code nothing happens to the view even though I already put header no cache and many times I cleared the browser history and pressed ctrl+F5. Now I am stuck to the view page from last 3 days and I already made so many changes in my source code. Please help......

Magento 1.8 admin account login shows white dashboard page

Without any change on system configuration and code since my last login, one day my admin account login shows blank dashboard page, header of the page is showed but most of content are blank. Big oddity is my customer service account is able to see her whole dashboard page and get her all backends working, however, as her account has system config part disabled, I can not do anything further.
After clicking login, the URL has showed up: http://www.example.com/index.php/admin/dashboard/index/key/8062533e7ee0df2d1d693d1d70148ad8/
I check HTML rendering, header div of the page has rendered, it stopped at navigation div. the last rendering seen as below.
<div class="nav-bar">
<!-- menu start -->
Could any master help out please, I have no idea where to debug....Thank you so much...
Try:
clean all types of caches
check permissions on folders(app/etc, var,
media) should have 755 or higher.
check logs(exeptions.log,
system.log)
enable errors reporting in
index.php(ini_set('display_errors', 1);)
Thank you all for replying...It is confirmed due to shoplift bug. I applied all patches including latest 5994 patch, nothing changed...I turned on error display in index.php, indicated an error file from includes/src, so I asked hosting admin to turn off php compiler, then I got my admin login back to normal....
However, not sure if this is side effect of the bug, I can not see all images of all products from backend, they all gone. weird thing is all images are good to see from frontend...does anyone know how to do housekeeping after site was being attacked by hacker?

White screen of death on admin and other dashboard pages

I have created a theme for the first time. but except the public area I cannot access admin by wp-admin. After changing he theme I saved redirected URL of admin which is this -->http://www.tennis-florida.com/wp-login.php?redirect_to=http://www.tennis-florida.com/wp-admin/&reauth=1, this takes me to login page and allows me to login then again none of the images are loading as they were previously mapped to localhost and now When I am trying to upload anything or add or modify post after licking submit button it gives me blank white page and I have to click back in order to get back to dashboard. So all in all the theme is completely useless. What I am trying to achieve is I have to ship this theme to client as they are already seen it and so I have to make it work.
As I said I have figured it out that the problem is with the theme(For the record I have created the theme by following a YouTube tutorial)
I am sharing all my codes
functions.php

index.php
http://pastebin.com/B9HXKzx8

style.css

sidebar was not required so haven't added anything in there, sidebar.php is blank.
That's all the files I have created apart from folders for images and all.
I have tried adding
ini_set('display_errors', true) ;
define('WP_DEBUG', true);
Even when I am trying to add a post and such with that another alternate admin link just after click publish wp shows blank page but the data is being added. to config and file and removing spaces in wp-config still no luck. Note: I cannot give up on theme as client has already seen this theme and I cannot provide another.
Note: This is a cross-post from wordpress.stackexchange.com as nobody answered this question.
I have already seen various other methods for solving this problem but its not working.
There's a syntax error in your PHP code which is what is causing the white screen.
SSH to the server and execute the files with the flag -l to check for syntax errors.
I am answering my own question as nobody has answered it yet and I have found the solution.
Upon some research I found about white spacing in php files. All I did to fix the issue was deleting blank lines from bottom of functions.php file, strange fix but worked.
