[BUG] Unusual Fatal Error, happening almost every 2nd day

[vdbhb59]

Describe the bug
The below error happens almost every 2nd day and at around 12:30-13:30 my timezone, and then automatically corrects itself after around 70-90 minutes from the timeline (around 14:40-15:00).

Fatal error: Uncaught Error: Call to a member function bindParam() on bool in /PATH/feeds/app/Models/FeedDAO.php:293

To Reproduce
Steps to reproduce the behavior:
No idea how to reproduce, as this happens automatically without me doing anything.

Expected behavior
This error should not happen and my feeds instance and feeds should show, instead I get just this error and no feeds show up.

It it always the same error you get? And is it only when you navigate to a given feed or do you also get an exception when you try to access a category or the main view?
It looks like a temporary database problem.
If you can, try to use our current rolling release 1.21.1-dev, which has changed some related handling of errors.

Hi Mate,
Sorry for the late reply.
I get the same error every time, same path, same file, same line.
I get it randomly, does not matter if it is main view, or a feed, or even a category. It just throws this same error randomly.
Temp Database Error: Probably.
Rolling release: How do I set it? I have a file "/data/config.php", where the value is: 'environment' => 'development', and something under it as "Salt" (I presume is some sort of encrypted connection value), which I am not sharing here. But how do I switch to the current rolling release, directly from the app itself, please? Cause even if I set it to "production", there is "Blast! No update to apply". Sorry for being a novice mate.

@Alkarex mate, closing out for now, as I have not been getting this error for almost more than a week now.
