Re: HELP!!!!

My guess would be that you have deleted a page that was set to the site home, login or user profile page. If you have a database backup, nows the time to think about restoring. If not, you may be able to fix with Sql, if my guess is correct. If this is the case, you will have to confirm in your database by running the Sql directly against the database: select HomeTabId, LoginTAbId from portals OR select HomeTabId, LoginTAbId from portalLocalization depending on the version Once you have these two values, confirm their existence by doing this: select * from tabs where tabid in (xx, yy) where xx and yy are the results for login and home tabs, from your previous query. If you're missing either tab, then that is the problem. You can either update your portal/portallocalization values with valid tabids, or set them to NULL This is just a guess, so it may not solve your problem. You will get back a list of the portals in the installaiton.
