[pmwiki-users] Double Custom Markup Prevents Page from Loading

Sat Nov 9 01:20:33 PST 2019

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
