Hello,

I have lots of Undefined error in SpiceCRM and also I have lots of error when I import Accounts

Is this permission problem?

What folder/files permission is necessary in SpiceCRM?

Yes, looks like permissions problem for the webuser
Directories require 775 permissions, files require 664

I changed hosting and now it works ok. But directories have 755 and files 644 and I think SpiceCRM work ok.

775 is unsecured permission, is it ok to use 755?

Important are write permissions for cache, custom and upload directories. 755 should be ok
