Re: [Phpwiki-talk] Troubles with PhpWiki recently developed

[Joby W. <joby@u.washington.edu>]

Johnny,

1) The error is caused when a variable is assumed to be an object of a 
particular type, but for some reason it isn't (probably a null).  Sounds 
  like it might have been a bad write (note there is no pagedata).

Does it fail on this page or all pages?

2) The error message says exactly where the files are:
/home/mark/public_html/phpwiki/lib/Template.php line 212
/home/mark/public_html/phpwiki/lib/WikiDB.php line 536

Which version of phpwiki are you using?  Without that it is pretty hard 
to figure out what is happending or you could post +/- 10 lines around 
the lines in question.
