Hello,  
I’m trying to install dolibarr using this tutorial: [Manual installation on Windows - Dolibarr ERP CRM Wiki](https://wiki.dolibarr.org/index.php?title=Manual_installation_on_Windows#Installing_and_configuring_MariaDB).  
I installed MariaDB, php8 and apache2.4 and I tested that all of them work correctly.  
I can’t finish the installation because when I open the site [localhost/dolibarr](http://localhost/dolibarr/install/index.php) I get the message _This page isn’t working right now HTTP ERROR 500_.  
I changed the MariaDB’s ports to 3310 and the apache’s port to 85.  
I checked all the extensions are uploaded by opening the php test file.  
So what else can I do to proceed with the installation?  
Thank you.

Hello,

Error 500 means PHP error: what does the Apache error log says?

Solved.  
To fix the _AH00558 error: ServerName is not configured on Apache Config_, I added the following line to the httpd.conf file  
_ServerName 127.0.0.1_

For the error: _PHP Warning: PHP Startup: Unable to load dynamic library ‘gd2’_ I removed the ; in the line _extension=gd_ in the php.ini file and I also copied the library _glib-2.dll_ to the folder _Apache24\bin_

Finally for the error _PHP Fatal error: Uncaught Error: Call to undefined function mb\_convert\_encoding()_, I removed the ; in the line _extension=mbstring_ n the php.ini file.

Thank you so much for your help.
