Funny bug, after transferring my forum to next hosting provider...

So I had to transfer my forum to new hosting, I copied all files from ftp, and I transferred everything to new hosting provider, now I have few errors, about 5 files with unexpected content, so I have these files, but content it is a bit different, for my this bug is a bit weird. Any idea?

Compare files and md5 data, if you have xenforo forum ,you need easy to check by files healthy system in backend
