Ok there seems to be other people having the same problem so let me start by saying, I HAVE PURCHASED Easy PHP Calendar.
In my admin for WP, I try to set the address but only get a 404 error.
Wordpress is installed
/var/www/html/news/
Easy PHP Calendar is installed
/var/www/html/news/c/
I have tried all combinations, moved the calendar to see if that helps but nothing.
Also When clicking Update Options, I get a error message saying:
Cannot load wp-easy-php-calendar-admin2Fwp-easyphpcalendar.php.
If I replace the "2F" with a "/" in the address field it works. So that might be part of the problem.
Thanks for all help
