Run Magento locally with error 500 - php

Question

I am having a online website and I want to edit my site locally with the use of XAMPP. Here are the things I have done below:
- Change Xampp port Listen 80 to 8080
- Install database to MySQL
- put my website files into htdocs
- change username, dbname in local.xml
- change web/secure/base_url and web/unsecured/base_url to http://127.0.0.1:8080/(my folder name) in MySQL database, core_config_data table
However, my website does not show after I have done all these.
It occurs Error 500.
what should I do for this to display my website?
After I change the permission and files to 777, I check for the error log in the xampp files (xampp\apache\logs. The error log shows below:

Solution 1:
If you're facing a 500 error then firstly you should search for the webserver error log, and if it's running on apache server it can mostly be found in one of these 2 locations:
Centos or Archlinux: /var/log/httpd/
Debian or Ubuntu: /var/log/apache2/
In xampp, you can find the error logs in \xampp\apache\logs\error.log, where xampp is your installation folder, if you didn't change the error_log setting in PHP.
Solution 2:
You can simply enable all errors by setting ini_set('display_errors', 1); from the index.php file of your Magento project, something like this:
index.php:
error_reporting(E_ALL | E_STRICT);
ini_set('display_errors', 1);
.htaccess:
SetEnv MAGE_IS_DEVELOPER_MODE "true"
You can also check errors in /var/log/system.log and /var/log/exception.log. in your Magento project's directory.
By default Magento errors output is off. If your PHP is not
configured to log errors then web server will return Internal 500 error in
case of fatal error.
OR maybe you're facing this issue because of the permission to your project folders, so the first thing you should look for error in the logs and then you can easily fix it.
But, if the issue occurs due to the permission then:
# Change folders permission to 777
app/etc
var
media
# Change files permission to 644
index.php (main index file in magento root folder)
downloader/index.php
