Installing my Dolibarr

Hello,
I have been attempting to install Dolibarr on my site. However, I keep getting the above error in Step 5. I’m not sure how to solve the problem. I did find a similar issue in the French forum (I used google translate to read it), and I have included the link; however, they never posted how it was resolved.

I attempted installing using Sourceforge download and GitHub, with the same error.

Plesk Obsidian 18.0.64 Update #1 Web Host Edition

OS - Ubuntu 22.04.5 LTS
MariaDB - 10.6.18
PHP vs - 8.2.25

Fatal error: Cannot declare class Contact, because the name is already in use in /var/www/vhosts/*****/httpdocs/contact/class/contact.class.php on line 44

Hello,

As explain on the french forum, this error seems to be related to the PHP configuration of Plesk.
Better to ask this question on their forum.
