Good day we were installing Dolibarr and changed the MYSQL and Apache Port .so after installation its giving the message

The resource you are looking for has been removed or had its name changed.

Kindly advise ,i am new to this

Please check the dolibarr directory name you have installed / upgraded on your server versus the virtual directory path you have mentioned in the .conf file in /etc/apache2/sites/sites-available/.conf
