I had enabled the newsletter signup on a maintenance page, I failed to test it to see if worked. After testing it seems that when Maintenance is enabled it disallows the block from going to the newsletter sign up page. The block does work correctly when Maintenance is off - that would indicate the block is okay.
Is there something in the maintenance page coding that would disable this?
I have tested this in 1.1.8 and 1.1.9 same result.
Thanks
