Solution:- Solved here. See details
Error 10:-
Solved- Class “Magento\Backend\App\Request\PathInfoProcessor\Proxy” does not exist
Reason & Solution 1:
First reason could be you have installed PHP 8 and Magento2 is not compatible with it yet. So to resolve this, you need to use PHP 7.4.
Reason & Solution 2:
Second reason we need to find with below steps:
-
- Open the bootstrap.php file present in the app folder of magento directory.
- Remove # from the beginning of the line
- #ini_set(‘display_errors’, 1);
- Save the file and refresh your browser to see the exact issue.
Follow this for more details.
Error 11:-
Apache Service detected with wrong path
Solution:
- Window + R and type regedit then enter
- Open this directory HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Apache2.4
- Right-click on the “ImagePath” and choose “Modify”
- Change the Value Data field with your current installed path of apache in XAMPP
- In my case, the value is “C:\xampp\apache\bin\httpd.exe” -k runservice
- For the question poster case, change the value to “c:\xampp\apache\bin\httpd.exe” -k runservice
- Close the Xampp Control panel and Open Again.

Thanks for contacting Nikhil Kishore.
Please follow below steps:
1. Remove semicolon from the beginning of the line ;extension=sodium from php.ini which enables it.
2. Copy (wherever you have installed xampp that drive )D:\xampp8.1\php\libsodium.dll to D:\xampp8.1\apache\bin\
3. Restart Apache means stop and start Apache.
Thanks,
Sonal
