i can believe this,in error log with today date i found rounded profile plugin error what this plugin has to do with cron job?

hey i founded it!!!!!

[Wed Dec 30 16:17:03 2015] [error] [client 178.59.9.121] FastCGI: server "/usr/lib/cgi-bin/php5-fcgi" stderr: PHP message: PHP WARNING: 2015-12-30 23:17:03 (EET): "Creating default object from empty value" in file /home/openplac/public_html/elgg/mod/roundedprofile/start.php (line 19), referer: http://.com/elgg/activity/cron/minute

Disable rounded profile plugin, seems like the cause.

i disable it and no its not that!

that log is my mistake because i dont use well the url its not elgg/activity/cron/minute

the right is the next one elgg/cron/minute and to that log says 

File does not exist: /home/openplac/public_html/favicon.ico

i give up...i cant find anything before few minutes i try to run cron/minute and i get internal error,after that i copy the error log file again and the last log was from 18:00 and greek time now is 1:30

@michele @manacim thanks for your time friends!

Hi πανος, I would suggest using [Elgg 1.8-1.12 & 2.X: Croncheck] plugin.

This plugin will show you which cron events are registered by Elgg core and 3rd party plugins for the cron intervals. Look for the events registered under your minute cron. This will definitely narrow down your hunt for the problem.

hi @rohit_1990_3676 i just used the plugin you suggest me,i saw that notifications and i zap videos use cron/minute i disable both plugins,run again cron/minute but again the same,internal error,somewhere as i search in google i saw almost the same and the reason was the lot of notifications piled up.(here https://elgg.org/discussion/view/1906148/group-notifications-problem)

i dont now...

good morning @michele no i run it manually because if i set up a sheduled cron with out solving the problem first i suppose will be useless.a lot of times i refresh  /cron/minute/ page but every time the same.each time  i run  /cron/minute/ page,server needs some time to be able to run again the  cron job/minute....
