Blank page on generate.form.php when asked to create a protocol

[leonardomavila]

Hi Everyone,

I had to migrate my server from Ubuntu to Windows Server (I know it's not the ideal, but it's the company policy), and since then, when I try to create a new protocol, I get a blank page on generate.form.php. GLPI running on ISS with PHP manager and Mysql.

This is the result on Firefox debug mode:

And below the log on php-errors.log:

[2022-05-24 10:04:40] glpiphplog.CRITICAL: *** Uncaught Exception TypeError: round(): Argument #1 ($num) must be of type int|float, string given in C:\inetpub\wwwroot\plugins\protocolsmanager\dompdf\src\Css\Style.php at line 3086

Do you suggest me something? Regards,

Solved. PHP version on new server was 8.0, while on the old server it was 7.4. Switched to v7.4 on the new server, and the protocols returned to be created properly.

Good afternoon Leonardomavila,
It shows me the following error when entering protocols manager, please support
Deprecated: Use CommonDBTM::getFriendlyName() in C:\xampp\htdocs\glpiper1\inc\toolbox.class.php on line 653
Deprecated: Use CommonDBTM::getFriendlyName() in C:\xampp\htdocs\glpiper1\inc\toolbox.class.php on line 653
The PHP version is 8.0.19 and glpi is 9.5.7
and when I click on the create button it takes me to this blank page

Use PHP 7.4
