What is the meaning of this error???

Notice: Undefined index: l_previousPage in /home/.sites/120/site35/web/bb_functions.php on line 205 Notice: Undefined index: l_nextPage in /home/.sites/120/site35/web/bb_functions.php on line 207

Where did i go wrong

Probably you didn't specify: $l_nextPage='Next'; in your language file?

Now i have added the following in my lang file;

$l_nextPage='Volgende';
$l_previousPage='Vorige';

Now i'm getting this error;

Notice: Undefined variable: prevNav in /home/.sites/120/site35/web/bb_functions.php on line 232

Any idea?

I've removed line 232 from bb_functions and now it's working!
Isn't that strange?

I'm not sure what kind of line do you mean, and what kind of miniBB version do you have.
In the current package, there is a comment on this line number, which obviously can't affect any code.
Definitely, removing something from the core file is not a proper solution, and that only means you still have some misconfiguration or improper setting on your end, which is impossible to determine without deeper debugging.

Okay.That's what i was afraid of.
I've put back the removed line in functions
and added

$l_nextPage='Volgende';
$l_previousPage='Vorige';

to my lang file and now the error is gone and everything is working as i should be.
So i'm happy.

thanks for the support

Above you also have written that after adding these lines, there appeared some error :)
So I'm a bit confused at this point as it's not clear what the problem was about, in general.

Yes, Paul I was also confused,
But first there was an error as told in my first topic.
So I specified: $ l_nextPage = 'Next', and $ l_previousPage = 'Previous', in my language file.
Still, there was an error on line 232 from bb_functions.
So I removed that line and it worked fine.
But as you said this is not the way to this problem.
Then I removed the entire bb_functions file and replace it whit the original file.
It worked fine.
I think I accidentally erased something in bb_functions file and that was the reason for the first error.
Once when the original file was replaced the errors disappeared

Ok, I hope you will know next time that the latest versions of all files should be installed prior to reporting a bug ;)
