possibly under preferences - I think you will need to be an admin There aren't that many places to look! I am running version 2 so can't really compare but it should be similar
yes, it's very outdated and effectively no longer maintained I believe there's a gedcom export although I can't remember how well it works in 1.4.2 That would be the first thing that I would try Depending on how technical you are, you could try updating to the latest version as that contains various updates/upgrades but that may not be entirely trivial gedcom is probably still the way to go
Which version of php are you using?
Support for PHP7+
I've just released 2.2.0 which should support this - sending a longer release email
Creating Branch 2.2.0
I have moved it to the sourceforge version of git which is a lot better than CVS! If you think that's not good enough then please open a new ticket. Back to the original ticket - it's nearly ready for a new release for php 7 - I'll try and do it next week.
More upgrade work
