How can we disable birthday extension when we don’t have access to dashboard?

actually I installed two plugins:
wp super cache
symple shortcodes by AJ clarke

but after changing and saving the settings, I checked the subdomain and there were no problem.. and then I don’t remember what actually I did that I encountered this error… the strange part is that my main site doesn’t have any problem but the subdomain shows this error
