Missing modules in the modules config section

Bug

The end of the page is missing

And this is the bug reported by PHP

: Uncaught Error: Call to undefined function mb_strlen() in /var/www/dolibarr/htdocs/includes/parsedown/Parsedown.php:170
Stack trace: #0 /var/www/dolibarr/htdocs/includes/parsedown/Parsedown.php(39): Parsedown->lines() #1 /var/www/dolibarr/htdocs/core/lib/parsemd.lib.php(53): Parsedown->text() #2 /var/www/dolibarr/htdocs/core/modules/DolibarrModules.class.php(702): dolMd2Html() #3 /var/www/dolibarr/htdocs/admin/modules.php(704): DolibarrModules->getDescLong() #4 {main} thrown in**/var/www/dolibarr/htdocs/includes/parsedown/Parsedown.php** on line170

I resolved it by installing the PHP extension
sudo apt-get install php-mbstring
sudo service apache2 restart

Hello @gherasasmaa
According to the wiki Dolibarr the mbstring php extension if database is not utf8.
Can you confirm it's your case please ?
