i've been fighting moving existing site godaddy windows 2012 amazon ubuntu instance, , no matter how many different ways try (bitnami lamp, bitnami concrete5 ami, direct install, direct copy-over, etc), custom theme not work. default themes work, , site works fine then.
the message get:
file /opt/bitnami/apache2/htdocs/updates/concrete5.6.3.3/concrete/themes/pndc/default.php not found. themes need default.php , view.php files in them. consult concrete5 documentation on how create these files.
does have idea going on, or how debug issue?
i got worked out moving concrete5 update "core" /concrete/ directory, , out of upgrade folder. changed app version , installed app version match, etc. seemed correct issue, can navigate , use custom theme.
