Cannot change profile settings

[huulong]

Repro:

1. Open Profile > Settings
2. Click on Save Changes (no need to change anything)

Error message appears:
Invalid pagination value, must be at least 2 and at most 20

@huulong please do as the message says, the value of paging is currently at 40 but it may not be more than 20

I had this problem too, changing "Topics per Page" and "Posts per Page" to 20 allowed me to save the new settings, but the default value was set to 40 and I think it's a bug, the default value is wrong

I also have this issue.
Thanks for the work-around, but maybe it's about time someone looked into this? Should be an easy fix :)
Maybe it only appears once for new members who haven't changed their settings before?
