One of the bugs I was referring to is the same admin problem. I tried your answer but it still did not work. Members from number 7 onward are still going under admin. Again, I am using just one link that does not have the admin as the sponsor or the referrer. Also please note: I saw a possible solution in this forum to change the My SQL database to:
Disable SQL mode in your server (e.g. remove the ONLY_FULL_GROUP_BY, ERROR_FOR_DIVISION_BY_ZERO, etc in the SQL mode).
If this is wrong, let me know.
This is what my hosting company replied with.
MariaDB [(none)]> SELECT @@sql_mode;
+------------+
| @@sql_mode |
+------------+
| |
+------------+
1 row in set (0.001 sec)
See the video for more clarification of the admin problem.
