Do you have all correct MyBB 1.8.22 files uploaded? What's the result of running a file verification?
If all files are correct, maybe you need to force refresh the browser to get the new JavaScript files, since your custom template doesn't update the version number of upgraded JavaScript files.

Could be wrong but worth a try.
