Open the config.xml file of the report (need to create a custom report)
Find those line:
<Report Template="individual.htm" OutputFile="{Name.LastOrLast2:25}-{Name.FirstAndMiddle:35}-{id}.htm" For="Individuals" LoopItemName="i" /> <Report Template="family.htm" OutputFile="family-{Name:70}-{id}.htm" For="Families" LoopItemName="f" />
You can either remove the name or reduce the max length... family-{Name:30}-{id}.htm
would be acceptable.
I will pass the word to change the default value for something smaller.
