Summary: Warning with preSaveTransform (possibly PHP 5.3
specific)
Product: MediaWiki
Version: 1.14.0
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Normal
Component: Page editing
AssignedTo: [email protected]
ReportedBy: [email protected]
This happened to my wiki after I upgraded to PHP 5.3. I haven't had this issue
before.
When I try to preview changes being made to an article (in part or whole) or
change the entire article, I get the following warning:
Warning: Parameter 2 to Parser::preSaveTransform() expected to be a reference,
value given in /var/www/wiki/wiki/includes/StubObject.php on line 58
When I try to preview an article, it just gives me the warning. I can't see
the preview, but nothing else happens. However, if I try to edit the entire
article (the entire thing, the bug doesn't occur when I edit a specific part)
and save the changes, it's followed up by an internal error. Here's the stack
trace that follows:
Original exception: exception 'DBQueryError' with message 'A database error has
occurred

(NULL,NULL,'utf-8')
