Hi,
I have a very bizarre side effect from a custom markup, and the most
bizarre is that it is a "new" problem in the sense that it has worked
in the past (I can't remember under which PmWiki version it worked
last, though).
The bizarre thing is that when, on a page, I invoke the custom markup
the second time, it prevents the save from working, the page stays
blank and does not reload. I am pretty sure that this is the cause,
because I went to some very old pages with the markup, and the pages
with only one instance of the markup load perfectly, but old pages
with two or more instances of the markup do not load anymore !
I have no idea what might be causing this as I am not that good at
programming and at PHP in particular, but I have copied the code of
the recipe below. My apologies for the probably very badly written
code.
Note that it's based on this:
http://ajaxian.com/archives/popbox-a-javascript-image-magnifier but I
am not sure how it's relevant to the issue... Note that I am using a
very old version of the script, do you think it might be the reason ?
Can anyone please help me solve this mystery ?
Thanks in advance,
Philippe
