[SOLVED] ***** ERROR ***** on file ****/model/Importable.php' at line (392) - by: Moophlles

Hi,
While I try to import datas from on instance of projeqtor V5.3.5 to an other with the same, I got this error on logs

2016-06-22 10:02:42.092 ===== TRACE ===== Importation : File type CSV
2016-06-22 10:02:42.092 ===== TRACE ===== File Name : ../files/attach//import/export_Project_20160622_100230.csv
2016-06-22 10:02:42.111 ***** ERROR ***** ERROR *****
2016-06-22 10:02:42.111 ***** ERROR ***** on file ****/model/Importable.php' at line (392)
2016-06-22 10:02:42.111 ***** ERROR ***** cause = Array to string conversion

the process is simply export project to csv form the first instance, then import on the second.

Please help me =)
