Drupal 8.x

Hello

I'm coming from Drupal 8.7, through 8.9 and I'm now in 9.3

Since D 8.7 I'm repeatedly getting this error whose I like to get rid of. I see it on every page request and it pollutes very much my watchdog. It doesn't seem harming anything though.

I've not the beginning of a clue and  couldn't find anything  that can help on Google.
If someone knows how to solve it or how at least remove this error from filling up my watchdog...

The banner on our (Drupal 8) town website is a photo image of autumn leaves.  I would like to be able to change the banner photo according to the season.  Could I use the Rotating Banner module to upload and sequence the photo images?  That is, can duration be set in days or weeks instead of minutes or hours?  If not via the Rotating Banner module, how else might a seasonal banner change be managed?

I am working with Drupal 8 on Linux and using bash and perl to automate certain steps post-installation to get to a reproducible state for further website development and testing.

Hi,

I have a weird issue since I moved to a new inernet hosting service : sometimes (but not all the time), when I navigate from an admin page to a normal page of my website, it looks like I'm logged out, but if I refresh the page, I'm logged in again.

I suspect a cache issue, but I didn't change my settings, and I'm not sure to know where to look. Any ideas ?

I'm on Drupal 8.9.20.

I am looking for a solution which where user email verification before the admin approval.

As in drupal if we select admin approval required user must be approved by admin first then an email trigger to user which contain the temp. password for first time logged in after then user verify that mail with that then he can logged in

Also what could be options (community and coding) to send notification to admin once user verify the email by customer.
