php errors on pages in mythweb

[ChrisLaw]

Description: Ubuntu karmic (development branch)
Release: 9.10

mythweb:
  Installed: 0.22.0~trunk22242-0ubuntu1
  Candidate: 0.22.0~trunk22242-0ubuntu1
  Version table:
 *** 0.22.0~trunk22242-0ubuntu1 0

        100 /var/lib/dpkg/status

When loading pages under mythweb, there's 2 php errors at the top of the screen. I suspect the second may also be causing problems with functionality, as hover-over text boxes no longer appear. nor do names of channels.

Warning at /usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php, line 16:
Cannot modify header information - headers already sent by (output started at /usr/share/mythtv/mythweb/classes/MythBackend.php:114)

I don't really know a lot more about this problem.
Cheers,
Chris

Typical - it might actually be that fixing 445873 fixes this too. I hadn't realised that until after filing, sorry.

I get a similar error with karmic:but newer version

Warning: Cannot modify header information - headers already sent by (output started at /usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php:49) in /usr/share/mythtv/mythweb/modules/_shared/tmpl/default/header.php on line 16
MythTV

I installed cleanly over the weekend - then shutdown myth and mysql and copied my mythconverg folder over from my old Jaunty installation. Every thing else (recording schedules, recorded programs, etc) seemed to recognise the old database schema and upgrade fine.

System details:

I've found other posts that say to try dpkg-reconfigure mythweb, or setting the hostname, but still not working. It looks like the script is working right up until the Modules::getModule call in the headers. No idea why.

[Ted Cabeen (ted-cabeen)]

sudo dpkg-reconfigure tzdata fixed this for me. (As suggested in https://bugs.launchpad.net/bugs/445873)

I found this:

Basically its because I coped the myth tables across and you can't do this for the mythweather tables.

[Mikko Rönkkö (mikko-ronkko)]

I have the same problem. When I copied over database from my previous installation that had MythWeather installed to a new installation that did not have MythWeather, the code fails because database indicates that MythWeather exists but it does not.

This was fixed with the following

cat << "EOF" | mysql -umythtv -p mythconverg
DELETE TABLE IF EXISTS weathersourcesettings;
DELETE TABLE IF EXISTS weatherscreens;
DELETE TABLE IF EXISTS weatherdatalayout;
DELETE FROM settings WHERE value = 'WeatherDBSchemaVer';
EOF

Apart from running this manually, I have no idea of what would be the proper fix for this bug.
