Ajax error on using list to filter calendar : error 500

[Draky50110]

What is the version of Jorani?

1.0 (master.zip)

Expected behavior

Load a popup to create and use filter by list on calendar view

Actual behavior

Gives an ajax error :

DataTables warning: table id=employeesOrgList - Ajax error. For more information about this error, please see http://datatables.net/tn/7

Steps to reproduce the behavior

Open a calendar view and select the icon to load a list of user to filter on calendar view...

Looking at Firefox web dev tools, it gives me a possible answer : an error 500 occurs when using this and JSON output gives :

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data

Not sure how you went with this
modify the codeigniter core/Output.php
Output php accordingly and give it a shot if you are running php8

replace the current
OLD line 457
$output = str_replace(array('{elapsed_time}', '{memory_usage}'), array($elapsed, $memory), $output);

NEWline 457
$output = $output ? str_replace(array('{elapsed_time}', '{memory_usage}'), array($elapsed, $memory), $output): "";

Sorry I don't remember how go to this issue.
I tested this software monthes ago and did not go further using it so...

Maybe this fix will help people.

I'd bet rather that the user installed Jorani on a MySQL Server where functions are not available such as a shared web hosting env.
But I'll add the PHP code as it doesn't harm.
