I have to say, I am very unhappy with this product. It seems to be very fragile and despite repeated support requests and fixes I have never quite managed to be able to fully utilise it.
The latest issue is that I cannot import members from a csv file. All is well, until it has started the upload, and then I get an internal server error. I could understand this if it did not import any data at all, but it seems to import some data and then stop. The latest list I am trying to upload has 76,000 email addresses. It imports 400 and then gives up.
I have allowed support access.
I have plenty of disk space and full privileges.
