Answer 1

Use this htaccess code
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /Magpie/
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]
</IfModule>
Step 2 :
Remove index.php in codeigniter config
$config['index_page'] = '';
Step 3 :
Allow overriding htaccess in Apache Configuration (Command)
sudo nano /etc/apache2/apache2.conf
and edit the file & change to
AllowOverride All
for www folder
Step 4 :
Enabled apache mod rewrite (Command)
sudo a2enmod rewrite
Step 5 :
Restart Apache (Command)
sudo /etc/init.d/apache2 restart
and use this url:
localhost/Magpie/Front_master/aboutus

Answer 2

Sometimes this is will come from the database issue. The error will show "Expression #8 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'tappo_stage_db.Ratings.rating' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by".Therefore you should want to run this command.
SET GLOBAL sql_mode=(SELECT REPLACE(##sql_mode,'ONLY_FULL_GROUP_BY',''));
