Hi JBW,
Thank you for your reply.
Unfurtunatly, changing the value at mytheme/template/catalog/partials/miniatures/product.tpl followed by:
backoffice, clear cache,
backoffice: force template
FTP: Clear smarty cache
does not give any change in front office.
I did fresh install dev-site and tried to change lenght product title to {$product.name|truncate:10:'...'}... followed by
backoffice, clear cache,
backoffice: force template
FTP: Clear smarty cache
No change in front office
What could I do wrong?
