this is my report when i run cron or the same i got in my email : i unchecked pdf invoice , increased memory limit in php and pockets in my.conf but the problem is not solved

i have a really serious problem with my WHMCS ... the problem is WHMCS does not generate invoices to renew for my clients the cron job is ok and i can see the emails for cron every day the dates and clients recurring date is ok i reinstalled whmcs aswell but i couldnt find the problem .... looking forward to hear from you
