Schedule message and log problems

Hi,

When I schedule messages in WordPress they don’t automatically appear on my facebook page, twitter page and in Telegram. Sometimes it goes well, but not anymore lately. Does anyone know how this is possible?

Also can not view the logs at the plugin settings there I get this error:
Y:| WHERE (flt = “snap” OR flt = “cron” OR flt = “sys”) |

I have already set up a CronJob.

The page I need help with: [log in to see the link]
