Losing add ons

ah, ok, thanks for explaining. Nope, never used addons.cfg.
I saw though that it said:

# A comma-separated list of actions to install (e.g. "mail,pushover")
action = 

# A comma-separated list of transformation services to install (e.g. "map,jsonpath")
transformation = map, jsonpath, RegEx,, XSLT

whereas i would expect those to be commented out like the rest?
RegEx is one addon i keep losing but JSONPATH is not.

I think this might well be connected to the sendMail problems I have been experiencing since a few days
