I have a Schecter Omen 6 electric guitar. I've always heard people tell me not to change all the strings at once but I wanted to clean my fretboard thoroughly so I decided to anyway.

Well, turns out I messed up my guitar somewhere, lol. I tried putting back a string on and it seemed like I messed up the height of the bridge and i would get buzz on almost all of the frets.

I was wondering if anyone knew how I could fix this or could direct to a guide of some sort to where it can show me how to set the bridge up and have my strings go through properly?

And just to make it clear, I'm a complete noob when it comes to this type of stuff. The most I do is change my strings and I screwed up this time, lol.
