[Forum] Error: Navigation element 1010 has no valid data.

[Evoklub]

I just upgraded from 4.1.2 to 4.2.0 P2.

The upgrade has run without any problems, then the forum worked as usual.

Then I wanted to adjust the navigation bar, first just modify the sequence of the "What's New" and "Forum". I changed the numbers, clicked to "Save" then I got this message:

Error: Navigation element 1010 has no valid data.

And from that, I couldn't do anything, instead if homepage come this:

Fatal error: Call to undefined function print_stop_message() in /home/httpd/www/evoklub.hu/html/forum/includes/functions.php on line 8670

And there was no way turning back, I had to backup the 4.1.2 version.

I tried it a few days later again, same problem. What can it be?

Can you provide a screenshot of what your changes look like?

Are you using PHP 5.2.0 or 5.2.1, by any chance? There's a bug regarding those versions of PHP here: VBIV-15239

Sorry I can't, I restored the 4.1.2, but all I was doing just modify the sequence numbers of "What's New" and "Forum". As I remember, What's New is 10, Forum is 30 by default. I modified 30 to 5, then came the error.

That would be why, you server is running PHP 5.2.0. Either upgrade PHP on your server or wait until vB 4.2.1 which apparently fixes this bug.

Matthew, thank you very much for your information.
