Plugin Causing Fatal errors & SQL Syntax Errors

Hello, dear ELEXtensions team,

We’ve been using your plugin for a while now, but recently an error started to show up that is causing issues to the normal functioning of our store, since it’s returning PHP fatal errors.

After analyzing our error_log we found the following errors that are causing it to break our store:

From a first look, the issue seems something to regard to cronjobs, but also there’s a SQL syntax error.

Could we get your help on this?

Thanks in advance!
