Expected and actual behavior

It's first time using REST api in dolibarr, I don't know, I guess to can explore the API methods :-D

Steps to reproduce the behavior

installing 16.0.5 in debian 9, apache2, php 8.0, mariaDB, installing REST api module and try it I guess.

Hello,

Dolibarr V16 is not compatible PHP V8. Please downgrade your PHP version to V7.4 or upgrade your Dolibarr to V18.

Hi @ksar-ksar ! And thanks for the response! In fact I already tried to change the PHP versión with no luck. Dolibarr throws the same error using PHP 7.4

Hi!

So... What?

cheers

Hello,

Work for me on V16.0.5 and PHP V7 Are you sure that all the PHP files are the one of dolibarr V16 ?

Hi @ksar-ksar

I'm going to compare using diff every file involved in the traceback, between our installation and a vanilla 16.0.5 source code. Is it all right?

Thanks!

Hi @ksar-ksar

I've just removed the htdocs folder and copy it back from a fresh new install of 16.0.5 and the same error persists :-(

What could I test or change?

thanks!
