Have you visited your wiki at all yet? If you visit it first, then try again, does the issue persist?

Yes it still happens even after visiting the wiki.

By any chance are you still using the vault/config.php from the Lite version? If you still have VW_IS_LITE defined as true, set it to false. You are probably missing some entries from your vw_nodetype table.

If they are missing, you need to add the following entries for the field 'accesskey':

Code:

Prefix Book Category Group Attach Redirect Special Topic AttachEdit Chapter CategoryItem Template Island Thread Poll

Particularly if these entries are not missing, please submit a Ticket Support service via the Members area, as we will need to take a closer look at your environment to determine why the 'Prefix' entry is not stored in memory (the 'Undefined index').

I accidentally had VW_IS_LITE still defined when I first updated from light to regular, but then I undefined it and did the upgrade again. Maybe that caused some issues?

I'll just uninstall and do a clean install tomorrow and see if that fixes it.

And yes, some of those entries are missing from the table.

After looking into this a bit more, I see that we designed it so that VW_IS_LITE should not have a negative effect on the upgrade process, but it seems that it did in your case.

Since you have this unique situation, it would be great if you can submit a ticket so that we can investigation your installation and determine what exactly went wrong. To submit a ticket, please use this link: https://www.vaultwiki.org/members/?d...e&productid=20

I submitted the ticket. Also, I forgot to mention that when the wiki is enabled, and a user who is not signed in visits it, they get a memory error. My php memory is set to 128 MB. I currently have the wiki disabled to avoid this error.

If you disable VW_CACHE_ON in your vault/config.php file, does the original issue persist? I have also sent you a PM.

Okay, I found the problem. A step was added to the Lite upgrade in the wrong position at some point (I think it was RC 2). The position of this step changed the offset of the update-the-addon-version step, which is supposed to be the last step to run. However, it looks like it was running before nearly every important step in the upgrade process, which caused the following steps to be skipped (it's already on the next version number, so why run the steps for the last version).

If your wiki is still empty, the simplest remedy for this would be simply to uninstall and reinstall. Please let me know if you have any problems doing this. I can't be sure if all the missing data will have an effect on the uninstall process.

Since it was a problem with the upgrade script, I am marking this issue as fixed and committing the fixed upgrade script to the Members area now so no one else runs into this issue.
