Hi Im upgrading my ip to latest, iv done all the required steps and everything has been done successfully but when I do /install/install.php im getting this Critical Error, anybody know how to solve this?  

I guess templates/prosilver_ip/ is not there since you deleted the templates folder (according to the manual)

I'm not sure why it's doing this and if uploading prosilver_ip would be the correct way to fix this TBH

Thanks Joshua203, i uploaded all the files within the ip_20120728_20086 pack and just kept the parts in relation to the upgrade procedure.
Just looked in the templates and as you say there is no prosilver_ip template, so I guess download that and ftp it to ip and it should find it LOL its just there's nothing about this in the instructions i.e. doesn't mention anything about requiring the template prosilver_ip?

Ill try that thanks

Must have something to do with your default theme settings?
But like I said .."I'm not sure", I mean should all this be reset by some action during install or what?

@batman

database_update.php is supposed to remove the old theme table(s) and create new tables with only the defaults in the package.

Did you run "database_update.php"

Or was that run "install.php" to complete the conversion?

It's one or the other?
