[pmwiki-devel] PHP errors and warnings

[Petko Yotov]

This probably comes from a recipe which saves some custom page attribute 
in the disk file when saving a wiki page.

If you're currently saving a page like Main.MyPage, look with a text 
editor at the disk file in wiki.d, either wiki.d/Main.MyPage or in a 
subdirectory like wiki.d/Main/Main.MyPage. In that file, the page 
attributes are at the start-of-line and look like this:

    author:123456=Simon
    csum:123456=My change summary

The warning comes from an attribute that has a colon ":" but it is not 
followed by a number (the timestamp).

Sometimes this can happen when a recipe saves a page via UpdatePage() 
and is trying to set the page attributes but the $Now variable is not 
defined as global. I suspect then you would have attributes like:

    author:=Simon
    csum:=My change summary

Alternatively it is possible that the recipe has a reason to use custom 
attributes that have a colon but after it they don't have a timestamp. 
Something like (speculating):

   food:lunch=Pizza

BTW the recipe may have already been updated and fixed. The page 
attribute stays in the disk file, until you delete it.
