Hello ! I have been using QuickPHP Webserver for years and was fully satisfied, (thank you) until yesterday when on a particular backup of one of my sites, I get the error message below :
Fatal error: Call to undefined function mb_convert_encoding() in D:\sauvegardes\revestou-20-aout-2015\include\functions.inc on line 439
As a result, I cannot browse the site, for it seems to my incompetent eyes, that the URL cannot be resolved.
What does that mean ? What can I do ?
Original website is online here : http://revestou.fr/
Thank you in advance.
