Ok so I just purchased mls_tournaments and I installed it on Joomla 1.5 and it doesnt work I get the following error message when I try to access it in the backend: Warning: require_once() [function.require-once]: Filename cannot be empty in /home/a9102489/public_html/administrator/components/com_mls_tournaments/admin.mls_tournaments.php on line 8

Fatal error: require_once() [function.require]: Failed opening required '' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/a9102489/public_html/administrator/components/com_mls_tournaments/admin.mls_tournaments.php on line 8

I am wondering why this is happening? Can someone please help me?

Did you read the notice on the download/order page? You also have to install com_mls_events for com_mls_tournaments to work.

from what i can tell this is due to the legacy plugin being used to install the component and then disabled after.

Source: trial and error

in any case will this and the teams component be fully ported over at some stage ?
