"CRON: There are 1 expiring relationships" What does it mean?

I’m using your membership 1 plugin(3.5.3.3).

But,When I update 3.5.3.3 from 3.5.2.7, All of my users saw “protected contents” message.

Maybe, Update program has something wrong.

So,I used Debug-mode.

This is the debug message.


[19-Oct-2015 17:12:30] loading level premium *<- this is my premium membership level I created.

[19-Oct-2015 17:12:30] Standard levels are loaded for current member.

[19-Oct-2015 17:12:30] Current member can not view current page

[19-Oct-2015 17:12:31] CRON: There are 1 expiring relationships

Do you have any idea?

I took a guess that my some membership DB-tables now have wrong data.

Maybe,3.5.2.7(old version) don’t use those data,so works fine.

But 3.5.3.3 is using them. (ex wp_m_member_payments),

So All of my member are force to move visitor-level in spite of their real level(premium).

Thanks.
