Emoncms "Error creating user"

Maybe I have found the possible problem:

The column “tags” from the table “users” is not installed as default null. That means that the DB expect a input for that column which is not given at the first registration.

The possible solution for that problem is:

ALTER TABLE `users` CHANGE `tags` `tags` TEXT CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL;

This could be solve the problem, but…

WARNING!

I think a developer should verify my post and agree if that solves the problem.
All other who use this change of the database make it on their own risk.

PS: I wonder very much that such kind of errors are not found at any logs! Why?
