There are a few problems with the UI of UM which has been there since v5. Sometimes you log in, and all the tables are blank. Well, the cells are all drawn across the page, but there is no user data populated into each cell of the table! You log back out, log in again, "bang" all the data is back again. Or sometimes you can log in and find the database has become read only. All the users are greyed out, you can't add any profiles or edit their private information, so you reboot the server and all is fine again. If you refresh the web page using your browser refresh button, the table does not update with any new data, but if you change to another menu in UM, then come back, "bang" the new data appears.
So many random and different things are happening that make us disappointed with the lack of development time given to this package. The problem is that when these problems happen we are in a hurry and do not have the time to document every single time and to take screen shots of every problem and then raise support tickets. I have now created a 6 hourly reboot of the server to try to get rid of the major problems (such as the database becoming read only on the UI). It has helped, but I am worried that these reboots will one day corrupt the database! Thank goodness for my hourly backups
(We have tested with many different web browsers and different operating systems so we know the bugs are within the UserManager not the Browser / OS.)
But this latest bug with PayPal's post back data not coming into UM is a VERY serious bug and caused us a lot of headaches. I have been told by MT that if they do not reply to your support ticket, it means they are either still trying to reproduce it in their test lab or they have agreed it is a bug and are actively fixing it, however I do not see it listed in 6.2rc1 changelog so they haven't fixed it yet, or they have, but haven't mentioned it in the changelog. Who knows.
