Hello,

 

I create a new server Windows server 2022, I installed IIS and mariaDB,Joomla with your component Akeeba backup and PHP 7.4.38. I import the file backup from my working website to restore in the same way.

I follow all the step for the restore and when all is done I try to open the front-end page and the back-end page but but didn't work. I see the white page like the attachment.

 

Can I have some resolution about my problem?

 

Thank you.

A white page or a page with a 500 Internal Server Error is, in fact, either a .htaccess issue to a PHP fatal error in disguise.

First, let's see if it is a .htaccess issue. Try renaming the .htaccess file in your site's root to htaccess.bak . If there is a .htaccess file in the site's administrator directory, try renaming it as well. If that solves the problem, the issue was with a directive in your .htaccess file. We'd recommend that you try removing directives from your .htaccess until you find the one which causes the problem.

If that doesn't help, the error you are receiving is in fact a PHP error in disguise. First, check your server's error logs (not the access logs) immediately after visiting the page which throws the error. There should be an exact description of the PHP fatal error which occurred. Sometimes you can find the error messages in files called error_log or error.log inside the site's root and/or administrator directories. If unsure about the error log location, please consult your host. Most likely the error logs are available in your site's hosting control panel.

If your host does not give you access to the error logs and you have access to the Joomla! administrator area, please log in to your site's back-end, go to Global Configuration, click on the Server tab and set the Error Reporting to Development. Try visiting the problem page again.

If you still get a blank page, edit your configuration.php file and put the following code right after the final closing curly brace ( this is what a curly brace looks like --> } ) but before the closing PHP tag (it looks like ?> that is a question mark and a greater-than sign):

ini_set( 'display_errors', true );
error_reporting( E_ALL ); 

Try visiting the problem page again.

If you still get a white page, please remove the two lines from your configuration.php file. Edit the .htaccess file in your site's root. If you don't have a file named .htaccess create a new one. Please note that that htaccess.txt is a DIFFERENT FILE and will not work. Add the following to the end of the file:

php_flag display_errors On
php_value error_reporting 32767

and retry loading the problem page.

If you still get a white page, remove the two lines from your .htaccess file. Now, create a file called php.ini with the following content:

display_errors=on
error_reporting=E_ALL

and upload it into your site's root and your site's administrator directory. Retry loading the problem page.

If that fails again, remove the php.ini file and create a file named .user.ini (note that it's dot user dot ini, the leading dot is important) with the contents:

display_errors=on
error_reporting=E_ALL

and upload it into your site's root and your site's administrator directory. Wait for 10 minutes. Waiting is important, .user.ini files do not apply immediately. Retry loading the problem page.

IMPORTANT: Sometimes the error won't show. Edit your configuration.php and find the line starting with public $error_reporting and set it to:

public $error_reporting = 'development';

This instructs Joomla! to enable maximum error, warnings and notices verbosity. In 99.9% of cases it will result in the error messages being shown on the browser.

If you still get a white page, delete the php.ini or .user.ini file your created and consult your host. They have to provide you the PHP error message, file and line it occurs (along with the error's backtrace) themselves.

Please note that if you can not understand what the PHP error message means, just copy and paste it here verbatim so that we can take a look and point you to the right direction.
