iFinity

There is a bug in the 1.14 series (and earlier) where the uninstall link doesn't work correclty on DNN 5.x  - this has been fixed in later versions, but that's not much help to you I suspect.

Go to your host->sql screen, and run this piece of sql:

select 'http://' + pa.HttpAlias + replace(t.Tabpath, '//','/') + '/tab/' + convert(nvarchar(3),t.Tabid) + '/ctl/Edit/mid/' + convert(nvarchar(4),m.MOduleId) + '/DesktopModuleId/' + convert(nvarchar(3),dm.DesktopModuleId) + '/default.aspx'
from {databaseOwner}{objectQualifier}Tabs t
inner join {databaseOwner}{objectQualifier}TabModules tm
 on t.Tabid= tm.TabId
inner join {databaseOwner}{objectQualifier}MOdules m
 on m.ModuleId = tm.MOduleId
inner join {databaseOwner}{objectQualifier}desktopModules dm
 on dm.FriendlyName = 'ifinity url master'
inner join {databaseOwner}{objectQualifier}POrtalAlias pa
  on pa.PortalAliasId = (select min(portalAliasId) from {databaseOwner}{objectQualifier}PortalAlias)
where tabname = 'module definitions'
  and moduleTitle = 'Module Definitions'

The output of the Sql should be a Url you can paste directly into your browser window to get the uninstall page.  Note that it just takes the first portal alias in your site - if this does't work try manually changing the domain name.

Try it with module%20definitions and see if that works.

Also, go to your module definitions page via the host menu and see if you have the same tab id (ie check tabid 18 is correct).
