Here's the thing...removing mythweather, music and news doesn't delete the<br>
corresponding tables, even if you use purge in apt-get.<br>
So when you reinstall and fire up the frontend, it gives the same<br>
complaints about the tables.<br>
HOWEVER, if you drop the tables after purging and reinstalling, the<br>
frontend log complains it can't find the tables in order to upgrade them.<br>
So purging/reinstalling doesn't seem to recreate/initialize the tables.<br>
I gotta sleep...but I appreciate your help. Hopefully you and others will<br>
see the issue and I'll fight the good fight when I wake up.<br>
Thanks!<br>

I'm surprised! I would expect the same proces that caused the problem<br>
to recreate the tables. How then if you add a plug-in to a running<br>
system? Normally on a fresh or updated system the frontend when first<br>
run does this!<br>

Each plugin has it own schema version and we store the version in the settings table so for MythNews it's 'NewsDBSchemaVer'.<br>
<br>
The database upgrade code looks at the schema version in the settings table and only attempts to update it if it is lower than the actually schema version.<br>
<br>
Assuming no update to the plugins was performed this looks like a DB corruption problem of some sort so running <a href="http://optimize_mythdb.pl" rel="noreferrer" target="_blank">optimize_mythdb.pl</a> would be a good idea.<br>
<br>
If you have dropped the MythNews table you will have to remove the 'NewsDBSchemaVer' schema version setting in the settings table to get the plugin to recreate the tables.<br></blockquote></div><br></div><div class="gmail_extra">Just to clarify your last sentence...if I uninstall Mythnews/weather/music, and drop their tables, I then set the corresponding SchemaVer to blank? i.e UPDATE settings SET NewsDBSchemaVer='';<br><br></div><div class="gmail_extra">For the record, here are the other values:<br><br>DBSchemaVer 1317 NULL<br>ArchiveDBSchemaVer 1005 NULL<br>GameDBSchemaVer 1016 NULL<br>MusicDBSchemaVer 1000 NULL<br>PhoneDBSchemaVer 1001 NULL<br>WeatherDBSchemaVer 1000 NULL<br>BrowserDBSchemaVer 1002 NULL<br>NetvisionDBSchemaVer 1004 NULL<br>NewsDBSchemaVer 1000 NULL<br>WebDBSchemaVer 4 NULL<br>GalleryDBSchemaVer 1003 NULL<br></div></div>
