>I’ve previously reported the issue once here,
sure , and I responded by saying you need to fix the session_start issue you are having . From what I can see (assuming we are talking about the same site still and looking at your debug log there ) it is still an issue on that site
(naturally, I have double-checked this here with the settings you provided above and it works just fine)

thanks,
am I right in thinking that you only get this issue when setting a custom range (i.e settings the 2 distinct from/to dates) in the reports section ?

Have a look in the plugin itself (sub)-directory /add-ons/gateway-development/ to see how to add your own gateway implementation (refer to the comments in the files).

However, if your question is actually about me doing this for you, I will have to disappoint unfortunately as I cannot offer customisations / one-off development .
Please see here https://docs.wp-pizza.com/faqs/?section=customisation.

So, I’ll have an update later today for this.
That said, just ignore my explanation regarding “>Issue 1” above. That’s not how it works and what I said is simply wrong.
The time do NOT get added to each other but are independent

i.e “Minutes after opening” applies only to the (re)opening times. (e.g opening at 8:00, 45min time set, 8:45 earliest available. once it’s later that that , the 45min become irrelevant)

Preparation times: always added to current time as earliest available slot (provided shop is open).
Naturally, “minutres afer openeing” and “Preparation times” might compete – so to speak – early in the day , so longest delay will apply

above just as a – hopefully understandalbe – explanation how this works if someone reads this thread

first of all, without a url where I can see things, I cannot really comment I’m afraid.
Furthermore, your third screenshot above is also missing the settings at the top of that page, which have an influence on how things work.
Lastly (for now): is the plugin up to date / latest version ?

> On other pages, if this above function is deactivated, the page works fine. And generally, I use the same theme and plugins everywhere.

I’m confused now . You have this activated from what I can see and it works on your site just fine now ? (And I did not change anything )
So what settings do I need to enable/dissable to get yoru problem please to reproduce this.

PS: you still really should address the session error as mentioned in my post above..

> However, on the order form, zip codes can still be selected.

of course. that’s the idea ….(?)

not withstanding my previous reply (i.e try that setting and I will see what happens here too) the seesion issue needs fixing too your end

>I will also send you the log file later.
ok
have you also deactivated all other plugins / used a default theme ? (to narrow things down and be shure)

Could you perhapos also post a screenshot of your postcode plugin settings ? thanks

first thing I would suggest is turn off your caching plugin and / or also re-save your plugin settings
furthermore , enable debug (https://docs.wp-pizza.com/troubleshooting/) and check your debug.log
let me know the outcome once you have done that
