Getting 500 server error just in the index page of laravel - laravel

Question

I am newbie to the plesk panel. The problem I am having is, I am only getting 500 server error in the index page. Other page of the same website opens perfectly except index. There is a following code in the .htaccess file of my project:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>
RewriteEngine On
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
What should I do to make the index page work like other pages? Do I have to add codes to .htaccess file?

Answer 1

It is not the index.php. The issue is about permissioning.
Execute
sudo chmod -R 755 folderforaccess
and
chmod -R o+w folderforaccess/storage
On live server you can do:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews -Indexes
</IfModule>
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]
# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
then also make sure that the php version in your composer.json is the same as that of your server.
Check your php version in your terminal using php -v
