子域中的CodeIgniter内部服务器错误

Question

I have deployed a website that uses CodeIgniter (http://www.myexample.com/) in the main public_html folder. In order to remove index.php from URL this has the following .htaccess:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|js|css|app|favicon\.ico|uploads|thumbs|assets|robots\.txt)
RewriteRule ^(.*)$ index.php?/$1 [L]

Now, I've created a sub-domain where I've deployed the same website in order to have a development environment (http://dev01.myexample.com/). I’ve copied the whole website in the folder public_html/dev01. However, when I try to go to the website I'm getting an Internal Server Error:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at [e-mail] to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

I know this is related to the .htaccess settings. However I'm not able to determine why this error is happening.

So far I've tried erasing .htaccess in both folders, or copying the .htaccess in both website folders. And also tried the following in the subdomain .htaccess file using relative path:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|js|css|app|favicon\.ico|uploads|thumbs|assets|robots\.txt)***
RewriteRule ^(.*)$ dev01/index.php?/$1 [L]

Does anyone know what could be the issue?

Answer 1

point your sub domain to dev01 directory through cpanel and use the same htaccess as your live project

RewriteEngine on
RewriteCond $1 !^(index\.php|images|js|css|app|favicon\.ico|uploads|thumbs|assets|robots\.txt)***
RewriteRule ^(.*)$ dev01/index.php?/$1 [L]

if you have put above htaccess code in dev01 directory it look for dev01 directory inside dev01 use this

RewriteEngine on
RewriteCond $1 !^(index\.php|images|js|css|app|favicon\.ico|uploads|thumbs|assets|robots\.txt)***
RewriteRule ^(.*)$ index.php?/$1 [L]
