Don′t know, if this occur problems, but you can edit your mysql-table with database-tool like phpmyadmin or sqlbuddy.
The Problem is, this plugin only let you create the number of teams multiply with 2.
So you have to change the number of teams to the half of real fixtures you plan to create.
Go to the table “wp_phpleague_league” and edit your specified league.
There you have to increase the field “nb_teams” to a higher number.
If you reload your admin-page you′ll see, that you can add more fixtures now, even if your old fixtures are deleted (anyway, dont know why :D)
I say it twice, dont know if this way broke anything in the plugin.
