(p) or paragraph text does not center align.

Hi! 
The parapgraph text that was nicely aligned in the center does align to left all of a sudden? 
Here is the website adress: www.tiego.se 

Any idea how this occurs? 
Did find anything in the css. 

Seems to be the whole webpage cause its even the menus are left-aligned. 

@tuanphan  @Ziggy any ideas?

You have this code (either in Custom CSS or code injection) that is limiting the width to 80% and aligned left which is causing the shift:

#block-ad998d005329e201e0e7, p {
    font-size: clamp(14px,3vw,18px) !important;
    width: clamp(80%,1vw,100%) !important;
    line-height: 1.6 !important;
}

because of the comma after the block ID this code is effecting all paragraph text.

That small mistake. 
Could not find it, thanks Ziggy!
