Thanks for the hint, didn’t knew about get_defined_vars
The tracker idea is nice and will also implement it as it will be good for cleaning up dead souls.
Additionally i stumbled on something minor. If user_nicename is not in latin it get’s filtered out (i.e. set to empty).
One of the purposes is relatively easy filtering of inactive members. I don’t want to import all of them or i will be stuck with the task of cleaning them. Just by having this i can leave the plugin active for 6 – 8 months and after that just shut it off.
A reinstall of the wordpress in a new DB fixed it. The problem seems missing in it.
The old DB is still available should someone want to look at it.
And i suppose i should open a ticket for WXR import mangling the attachments
