I suggest that you always update the table "mlf2_temp_infos" with the latest version. A quick SQL query run once per day doesn't slow down the web site.

Yes. Better would be (IMHO) not only to compare the installed with the reported version numbers, but also to compare the stored, yesterday reported and the newly reported number and only white to the database, when …

- … these two numbers are different or
- … there is no reported value or
- … if the newly reported number is different from the number of the installed version.

I agree.

Besides from that, the query should and does (?) run once per day. Please report the value of the setting next_daily_actions and the time, when you read it from the enhanced settings (date, time, timezone).

It does. I manually edited the database and set the field "next_daily_actions" in the table "mlf2_settings" to zero and forced a run of "checkUpdate()".
