Why are so many things 'undefined'?

I have Version 7.2.1 Sugar Version 6.5.20 (Build 1001)

My CRM seems to be working fine but so many things have ‘undefined’ on them. Error messages, pop up messages, labels. I have read on forums that it may be some sort of permissions issue but I checked them on our server and they all seem to be correct. Folders are 755 and most files are 644

Is there a cure for this?

Thanks in advance for any help,

Dave

Hi Guys,

this turned out to be a file permissions issue and it’s working fine now.

I downloaded FileZilla FTP client and this made it very straightforward to make changes to the permission of files and folders en-masse. Very pleased with it.

Kind regards,

Dave
