Main bug.
A new user can't at all connect and get a blank screen.
This without crash.If the user have an analyser he will find that tiki has sent this code
The page sent contentCopy to clipboard<html><header</header><body></body></html>- Solution
Note : I had redacted this before a commit but I used the "close button" of "code" plugin which have cut off a large part of my text, and I had a net cutoff just after. So I reproduce here (main page) my solution (which have been detailed in comments). Later Chealer got on the subject.
Probably and surely avoid that $_SESSION'attributes' should be not null, but not only in my opinion.
But as the developer writing, when user is null (new one) the instruction
The actual instructionCopy to clipboardarray_merge($prefs, $_SESSION['attributes'])
has the aim to keep $prefs values even $_SESSION'attributes' is empty (first start)The fact that array_merge($prefs, $_SESSION'attributes') returns "null" for any reason (bug in SESSION old DATA etc...), is always an error (if an array is null the instruction array_merge returns an array null in any case).
So the right instruction which answers to the developer aim is (because $prefs can't be null)
The suitable instruction in any caseCopy to clipboardif (! is_null ($_SESSION['attributes']))array_merge($prefs, $_SESSION['attributes']);I commit this changes the 19th which has been immediately rewind to be sure that the bug remains...
I don't understand Chealer decision(see the comments).Waiting for Chealer solution and remarks, may be I have not seen something.
To go farther... I let Chealer go on.
- Workaround
Spent near 12hours to find that in user_prefs.php if the data come from another version the $_SESSION'attributes' is a null area.
when merged with prefs default we get null prefs which automatically crashes the execution.- Priority
