Yesterday I installed SMF to my website and I tried to change background of the forum ( I use Boru theme ) but it didn't work, it was again showing default background, Then i gone to website throught my phone and i saw that background is there, on my computer it is not but on mobile phone or any other device that is not previously gone on the site it is. Also, i put a banner on site ( at the bottom ) and i gone to site via Google Chrome and it wasn't there but i opened Windows Edge and gone to site and banner was there. I dont now what is happening, cache is not updating or? Somebody can help me please? Thanks! ( Sorry for my bad english )
