    More then 20 days and no answer here ? What kind of support is there ? I'm having a lot of problems after migrating from vb4 to vb5, and felling alone by myself.

      VB5 has 2 config.php files, you must fill them both out.

      Then you need to run the upgrade script like with any other VB upgrade.

      Make sure you backup your database before attempting to upgrade.

      I am sorry about the 20 days without an answer, in the future feel free to "bump" your thread after a couple days- if it gets too old likely we'll never see it even if answered. 2 to 5 days is fine to "bump" a support thread so long as it's on a supported issue, like this.

        Joe, good to know you're alive. I just bought the license yesterday. My problem is that, after upgrade, I can't login. It seems it authenticate my user but don't get the session. After I put my user name and password it tries to login and return to previous screen but my page acts like I am a visitor. The only change is the URL that gets an question mark and a sort of Id appended to it. Like this: "?_=1363920292420"

        The same occurs if I try the administration login.

        If I try the lost password option, I just get an grey empty screen, just the background of the default style.

        Any clues?

          I see you have a VB4 forum on the same domain.

          I suggest changing the cookie prefix in the 2 VB5 config.php files to something else, maybe bb2 instead ot the default bb so we can eliminate the possibilities cookies are causing the issue.

          Remember you must make the change in both config.php files.

          Also, If you manually add the s after the question mark, does the page work?

          That is to say, change: ?_=1363920292420 to ?s=1363920292420

            Good day Joe,

            Let me tell more about my case.
            I first installed the vb5 in a blank database, and everything worked allright. Then I just dropped all tables, restored the vb4 database on it, and runned the upgrade script. The upgrade process runned with no erros. But I can´t login.

            I've tried your suggestions, but it didn´t work.

            I think it´s not cookie related because the site worked when I installed on a blank database. Just after migration I had this issues.
            Hey, I've change the debug config to true, and now I'm getting this error on the registration page. Maybe it´s a bug or something wrong. Look:

            Debug: Error
            Invalid Page URL
            occurred in file /home1/intelig9/public_html/vb/includes/api/interface/collapsed.php on line 114
            • Function relay in file /home1/intelig9/public_html/vb/includes/vb5/frontend/controller/relay.php line 56
            • Function legacy in file line
            • Function call_user_func_array in file /home1/intelig9/public_html/vb/index.php line 141

            Thanks for help.

              I've digged into the code, and found out that it tries to reference the "register.php" file.

              It expects it to be in the path: [baseurl]/core/register.php
              but this file doesn´t exists there. It´s on [baseurl]/core/vb/api/vb4

              If the site works on a clean install and has this kind of bung on a "upgrade" install, it may be some wrong setting value stored on database, I think.
              Any clue on which table should I look for ?

                  You don't still have the vB4 files in the same directory as your upgraded site do you?
