When i want to load into my modded version it constantly says:"There was a error loading optifabric, Failed to load optifine please report this" So i went here and now im asking for help on what to do cause i have no idea.

do you mean modded version of optifabric if so then you need to figure that out yourself you modded it afterall, read your log & crash report

There will be a Copy stack-trace button on that screen, if you click it and paste the result here that will help know what has gone wrong. If you're using an old version of OptiFabric it might be worth updating and seeing if that helps any too.
