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.
