MAMP Support Forums

There is very little said in the forum about WP Duplicator PRO. I installed MAMP earlier in the week because it was highly recommended over WAMP / XAMPP.

After installing it everything appeared to work correctly so I place my Duplicator ZIP and accompanying installer.php in the document root directory. When I set up up to run localhost/newsharoniowa2025/ the directory appears as Index of /newsharoniowa2025 with the zip file and the installer.php file. When I use localhost/newsharoniowa2025/installer.php I receive the following error message:

This page isn’t working
localhost is currently unable to handle this request.
HTTP ERROR 500

What needs to happen for this to run my installer.php request on a Windows 11 machine?

Laying Duplicator Pro aside -

I copied a full WordPress site into the Document Root, but I still cannot access it through MAMP. I received the same error -

This page isn’t working
localhost is currently unable to handle this request.
HTTP ERROR 500

That leads me believe that there is a setup issue with my installation of MAMP. I have uninstalled/reinstalled it several times and have had no success it access my development WordPress site.

Any ideas what may be causing this error?

Looking at my wp-config file there is the following error message:

[03-Feb-2025 06:55:20 Etc/GMT+6] PHP Warning: Unknown: Failed to open stream: No such file or directory in Unknown on line 0
[03-Feb-2025 06:55:20 Etc/GMT+6] PHP Fatal error: Failed opening required 'C:/Users/rlmcc/OneDrive/htdocs/newsharoniowa2025/index.php' (include_path='.;C:\php\pear') in Unknown on line 0

Issue has been resolved -

I was using ONEDRIVE for my htdocs folder and when I moved the folder to DROPBOX everything began working correctly.
