XF 1.3 Errors after upgrade

I am getting this error since the upgrade when I try to post anything :

    ["_xfResponseType"] => string(4) "json"
The replies get posted but an error comes up after I hit reply. Any ideas how to resolve this problem?

I installed a new copy of xenforo and upgraded another one on the same server with no problems, its just this one which has errors.

It sounds as if the files haven't been uploaded correctly.
You could try uploading them again - don't use FileZilla, it's rubbish, try something like WinSCP.

What is the error shown in the console?
Use the browser inspection tools to check.
I uploaded the files again using winscp and everything is working fine. Some files probabbly got corrupted while uploading using filezilla. Been using filezilla for more then 10 years now.. I guess its time to say good bye at last.

There are no errors anymore.
