Yes, using the tool for MyBB 1.8 and current board version is MyBB 1.8.30.
If I knew what the fields would output, that would help a lot. There is a check or at least I guess it looks for files and can't find anything. Is there a pre check or does it instantly start downloading but can't and gives an error?
EDIT: I did check beforehand with the compatibility checker which was 100% OK. But could it be a file size issue that throws this error?
Yes, I tried, didn't solve the issue. But thanks again!
