There is a bug when running the updater from 3.6.2 to 3.6.3. When phplist 3.6.3 is downloaded to tmp_uploaded_update, it is downloaded to directory phplist-3.6.3. The trouble is the updater expects the the directory to be tmp_uploaded_update/phplist NOT tmp_uploaded_update/phplist-3.6.3.
Resolution: The updater says “Downgrade is not supported” until tmp_uploaded_update/phplist-3.6.3 is renamed to tmp_uploaded_update/phplist

@cschmitt The updater hasn’t changed in a while, this looks to be an inadvertent change to the top level directory in the download file. As you say, the updater expects it to be “phplist” but is now “phplist-3.6.3”.
@mariana Do you know how to revert the directory name in the zip file? The updater code expects it to be simply “phplist”, e.g. line 527 of updater.php
Thank you for this information. I too was on 8 and not only could I not get to the admin screen, It missed sending a couple of pre-staged campaigns! Dropped back to 7.3 (native to my server) and all appears well again.
