site off-line, unable to login as user 1

This is in 4.7 RC3 (test situation), site set off line.

When you login a different user as user 1, that user keeps coming back in the url. The site stays correctly off line but does not allow logging in as user 1 anymore and thus won't ever come out of off-line status anymore in a normal way which is undesirable.

Work around for me was to edit the variables table manually and clear the cache table.

Have to say, the off-line function is a very useful addition

Thanks, Johan

PS not sure I've reported this under the right module
