Parse error: syntax error, unexpected '.' in themes/icynets-simplic/inc/customizer.php on line 437

That’s saying there is a period or ‘dot’ where there shouldn’t be.

Renaming the theme would at least make the site recovered(force deactivation of theme), then you could access the WordPress dashboard again if you don’t have FTP

Then you could use the WordPress editor to make the edit you need possibly.

I hope that helps, I’m kind of new to the forums coming from the support side
