Extensions Crashing My Site

Hello,

I want to install extensions but when I activate more then 1 of them on my admin dashboard this error occurs on website:

This happens with emoji picker, spoiler alert, Anyone have an idea?

Also some extensions like flagrow uploader and gamification crashes dashboard too with a different url (nojs)

clear cache your browser and than try again ?

FebriTriHarmoko It worked with first issue thank you mate. Can you check the second one too?
