I cant see any obvious errors in log, just login errors.
When I edit a few of my accounts it says at the top of page in red "this may be a duplicate" and displays green buttons at bottom of account page, 'Keep', 'merge' delete others' etc.
Overall I have 1125 individual accounts.
In admin under duplication checker, 86 are showing as duplicates, but I cant see why?
business names are different, contact details are different.
There is no information I can find in userguide or wiki about duplicates, what constitutes a duplicate, how the crm checks for duplicates (in fact a search of the word 'duplicate' returns one result -and its not related to the duplication system).
Can you provide more information on what the system checks for when looking for duplicates?
