I was able to make it work with /forum; no ^~ required. Given what @yariplus stated this seems relevant.
Indented lines are ones that I copied from my other blocks that weren't present in the suggested.
After today upgrade to 1.7.0 we observe a significant increase in errors leading to process dying and being restarted.
Seems to always be preceded by this stacktrace:

Would you care to take a look? Thanks!
