Your PHP installation doesn't meet the XF minimum requirements.

It is missing the iconv extension.

Your right, It’s been working fine for 2 years ?
I contacted my hosting company.

A update to PHP might not have had or enabled.

fixed.
from host.

Upon checking the server, we could see that iconv extension is missing for PHP 7.2 version. We have now enabled the PHP extension.
