[Chameleon] Session error due to a problem drawing the map

Hi Jacob,

First of all, thanks for your reply.

I’ve done what you suggested and I have to say that it seems to solve the
problem to me as well. I’ve been testing my apps quite a lot and the error
has not occurred again.

I changed my php.ini, loaded the php_mapscript.dll extension by default and
it seems to fix the error, at least for the moment.

Anyway, I’ll keep on testing to see if this is really the source of the
problem (it seems to be by now) and will write again in case the error
happens again.

Thanks a lot for your help, Jacob.

Hi Rafael,

I have been playing around with this since then, and it *appears* that the
error goes away if you load the php_mapscript extension by default. I'm not
sure if this is a fix or a patch, but I think this works. I also made some
minor change to session.php before that, but I don't believe that actually
fixed anything.
So change your php.ini file, try to load the php_mapscript.dll extension by
default, and see whether it works.

I'd be interested to hear whether this fixes it for you.
