An important bug has been fixed in version 1.2. A new corrected version (1.2b) is now available for download. Registered users will get the new download link today.
Apparently, I forgot to do one crucial test after maken a small last minute change, just before releasing the last bug fixes (1.2b). As a result, gedcom import was no longer possible. If you have version 1.2(a), just upload the corrected file /includes/classes/gedcom.php to fix this bug.
If you still have an older version than 1.2(a) and want to update, you will have to do a full update.
Note that the version number of your installation will still say “1.2”, even if you do a full update to version 1.2b.
