[FIX] RE: cron run not completing & blank pages

Recommended Posts

It is critical that you check all modules/hooks when you upgrade to version 5.2


There was a change to the way in which that will mean your old modules and hooks will need updating to the new way of doing things.


If you are having issues with the cron job not completing or if you are seeing blank pages client side and enabling php errors from the admin area side does not highlight anything then you have a high probability that an old hook or module is the cause of this.


Any old modules you use and any hooks should be backed up. Then you can remove them from the system.


Once you have everything running again you can check things are working.


run the cron job in whmcs/admin/cron.php from a web browser. as long as you are logged into whmcs admin area, your admin user will be the one that runs the cron job instead of system. but you will sytill be able to check if it completes.


If you see you have fixed blank pages/the cron job you can then one at a time add in the modules and hooks, only upload the next once you have verified the last one.



Good luck with this issue.
