Hi, I'm trying to understand, why table : "xf_session", reaches the size of 500 Mo. After several posts I had understood and concluded that my setup was poorly done. Since I update 1.3.3 to 1.4.10, I would like to sort. What can I do for this xf_session? To clean or purge. Because 500 MB for this table is just insane! Not take into account the 'xf_mail_queue' on this screen, because this is solved with the update and I emptied it and mails leave normally. Thanks for your responses and help. Kind Regards, Yoann.M P.S: Excuse me for bad english, I'm French.
