[pmwiki-devel] Pmwiki bug in SideBars (Pm?)

[The Editor]

Still having troubles with ZAPforms in the Sidebar issue.  I'm
thinking it might be a bug in how PmWiki processes the sidebars, as
the forms work perfect everywhere else in the page.  Even multiple
forms on a page....

Below is the markup that is causing the problem.  The only part that
is causing the errors.  I also included once again the error message.
If anyone has any suggestions, I would definitely appreciate it.  I
would even settle for some tips on how to debug this thing.  Don't
have a clue what to check or how.

Right now I have hardcoded a jumplist menu, but I really need zap in
the sidebars. Hoping someone will have a brainstorm...

Cheers,
Caveman

PS.  It works fine in my home machine, so perhaps it is a php or
server configuration error?  Something to do with caching?  I'm
clasping at straws. My home and server config files look virtually
identical....

Here's the error message.  It shows up in the sidebar as well.  Line
452 in ZAP is in the function above.
