newBB 5.1.0 error admin

Good morning. I'm trying various modules on the updated site.
The newBB module gives me the following error on the administration side:
Error: Error: Call to undefined function exec() in file /modules/newbb/admin/index.php line 74
Can you help me?

Re: newBB 5.1.0 error admin

It is possible that your PHP configuration isn't allowing the core function exec to be used
The function is often disabled on shared hosting servers, so check the php.ini file on the server and make sure that ’exec’ is not listed as part of "disable_functions" in php.ini

You can also check using the phpinfo() - see here how to do it

Re: newBB 5.1.0 error admin

If there are still problems, try to replace the function in /modules/newbb/admin/index.php starting on line 68:
function newbb_getImageLibs()
{
    
$imageLibs = [];
    
//    unset($output, $status);
    
if (== $GLOBALS['xoopsModuleConfig']['image_lib'] || == $GLOBALS['xoopsModuleConfig']['image_lib']) {
        
$path = empty($GLOBALS['xoopsModuleConfig']['path_magick']) ? '' $GLOBALS['xoopsModuleConfig']['path_magick'] . '/';
        @
exec($path 'convert -version'$output$status);
        if (empty(
$status) && !empty($output) && preg_match("/imagemagick[ t]+([0-9.]+)/i"$output[0], $matches)) {
            
$imageLibs['imagemagick'] = $matches[0];
        }

        unset(
$output$status);
    }
    if (
== $GLOBALS['xoopsModuleConfig']['image_lib'] || == $GLOBALS['xoopsModuleConfig']['image_lib']) {
        
$path = empty($GLOBALS['xoopsModuleConfig']['path_netpbm']) ? '' $GLOBALS['xoopsModuleConfig']['path_netpbm'] . '/';
        @
exec($path 'jpegtopnm -version 2>&1'$output$status);
        if (empty(
$status) && !empty($output) && preg_match("/netpbm[ t]+([0-9.]+)/i"$output[0], $matches)) {
            
$imageLibs['netpbm'] = $matches[0];
        }
        unset(
$output$status);
    }

    if (
function_exists('gd_info')) {
        
$tmpInfo         gd_info();
        
$imageLibs['gd'] = $tmpInfo['GD Version'];
    }

    return 
$imageLibs;
}


with this code:

function getPhpInfo($section INFO_GENERAL)
{
    static 
$infoCache = [];

    if (!isset(
$infoCache[$section])) {
        
ob_start();
        
phpinfo($section);
        
$infoCache[$section] = ob_get_clean();
    }

    return 
$infoCache[$section];
}

function 
newbb_getImageLibs()
{
    
$imageLibs = [];

    
// Check for GD library
    
if (function_exists('gd_info')) {
        
$tmpInfo         gd_info();
        
$imageLibs['gd'] = $tmpInfo['GD Version'];
    }

    
$info = (array)getPhpInfo();

    
// Check for ImageMagick
    
if (== $GLOBALS['xoopsModuleConfig']['image_lib'] || == $GLOBALS['xoopsModuleConfig']['image_lib']) {
        if (
preg_match("/ImageMagicks+([0-9\.]+)/i"implode(" "$info), $matches)) {
            
$imageLibs['imagemagick'] = $matches[1];
        }
    }

    
// Check for NetPBM
    
if (== $GLOBALS['xoopsModuleConfig']['image_lib'] || == $GLOBALS['xoopsModuleConfig']['image_lib']) {
        if (
preg_match("/netpbms+([0-9\.]+)/i"implode(" "$info), $matches)) {
            
$imageLibs['netpbm'] = $matches[1];
        }
    }

    return 
$imageLibs;
}


and let me know if it helps.

Thank you.
I tried removing "@", but the error remains.
Tomorrow morning I'll try this second solution and let you know
