This is already done, i have read, and yes i have un-installed the cb invite plugin (i don't have any other CB plugins installed a part the one that come with the default CB instalation) the problem is not corrected when the cb invite is deleted, so i installed it back, i published it, and my problem is diferent but the result is the same : a blank page. since the re-instalation of the cb invite plugin, the only diference is that i don't get anymore the language error message. just a blank page.
Any hint or should i go back to the old CB suite version ?
