php_handlers_control --rereadthe following error appears:
# /usr/local/psa/admin/bin/php_handlers_control --reread
Domain "example.com": the PHP handler "plesk-php71-fpm" is not registered. It was probably deleted from the server. Register a handler with the same properties and try again.
PHP version in domain's settings was not changed to a different one before the removal of PHP version.
- Log into Plesk.
- Reinstall the removed PHP handler version with this instructions, e.g. PHP 7.1.
- Open Tools & Settings > PHP Settings and check which domains remain assigned to the version needed to be removed.
- Change PHP version of all domains found on step 3 to other available version, e.g. PHP 8.1.
- Remove the PHP handler version again with this instructions.
