update:
I overwrite all fiels now with fresh PP 562 files of a donwload of yesterday. So very recent
After that I deleted again the usergroups in PP database except admin and did the sync in ACP. But still in the db of PP the users are part of the old UG-ID.
What else could it be?
Shall I now do a fresh import into a fresh
vb forum withy your script again and try the sync afterwards again?
