Import large amount of data

Hello everyone ,
i currently want to import a n excel file with more than 200 lines into the module account.
Everytime i do this i realise that just a certain number of lines are imported into suitecrm (in this case always 60 lines) and the rest is not being imported.
I checked on the crm parameter and there i have allowed suitecrm to import more than 1000 lines . This apparently doesn’t change something .
I don’t know if someone had this issue already .
Every solution is welcome

have a look at line 59-61, maybe the csv contains a “broken” line that interrupts the import (e.g. check for additional double quotes).
