Finally found a fix so I'll repost it here in case anyone else has this problem.
You can read the full thread
here.
I'll post the solution here too:
Edit the file
modules\mod_eventlistcal15q\
mod_eventlistcal15q.php at line 135 you will find this code
Code:
if (empty($myurl))
{
$request_link = 'index.php?';
}
else
{
$request_link = 'index.php'.$myurl;
$request_link = str_replace("&el_mcal_month=".$req_month,"",$reque
st_link);
$request_link = str_replace("&el_mcal_year=".$req_year,"",$request
_link);
}
and change for this code
Code:
if (empty($myurl))
{
$request_link = $uri->toString(array('path')).'?';
}
else
{
$request_link = $uri->toString(array('path')).$myurl;
$request_link = str_replace("&el_mcal_month=".$req_month,"",$reque
st_link);
$request_link = str_replace("&el_mcal_year=".$req_year,"",$request
_link);
}
