CMS Made Simple Forums

I just noticed the same problem with 2 different websites! To test it, I setup a clean "test" install of CMSms 1.6.6 and downloaded both CGCalendar and the old Calendar module, entered 4 events (2 for each category) in each module, then checked the results.

Sure enough, CGCalendar reverted back to ALL categories when the next/prev month arrows were clicked, while the old Calendar worked correctly, showing only the category listed in the module call.

I'm sure there's a "smarty" way to fix CGCalendar, but until I figure it out, I guess I'll have to downgrade our sites to the older Calendar module. Rats!

I have the same problem going on.  The only fix I found anywhere on the site here was to add inline='1' and that didn't seem to work.

I got it sorted by editing the module and adding a line or 2 to function.displaycalendar.php

Essentially I added this:

if($category) {
    $parms['category'] = $category;
}

Below the section where the params are set to create the next and previous links:
$parms = array();
$parms['use_session'] = $use_session;
$parms['year'] = $next_month['year'];
$parms['month'] = $next_month['month'];

and before the actual links are made.

I am not comfortable editing the core files of the module like this and it is not a smart way to solve the problem.  It is not tested.  If this is a bug in the module however and the fix makes sense to the module developers perhaps it could be added?
