>but the widget loads in an empty Theme site
what widget please ?

That said, if you are using the “Avada” theme, then the fault is there and they need to fix this – they know about this but seemingly refuse to do anything about this .
(Regardless of what they say, they are simply using the ‘the_content’ filter multiple times on the same page – with the results you can see )

As I know nothing about the “Pizzon” theme, all I can only really say is :
Does it work as expected with a default 20something theme ? If so , it’s a question for the “Pizzon” theme developer

As it’s all a bit abstract though, do you have a screenshot of your thank you page you can share ?
Ideally with some comments as to what you expect there to be different if it’s not that obvious

PS: woocommerce usage (or not) is not relevant .

as you are using a commercial theme I can only advise you to the usual troubleshooting as per
https://docs.wp-pizza.com/troubleshooting/

if you disable all plugins except the main wppizza one and only get the issue with the theme you are using but not any default theme , you will have to speak to the theme author.
I will not be able to advise you as to what your theme’s issues may be (as it is commercial, I will not be buying it as i have no use for it)

PS: You should make sure to also check your javascript console too for some clues

works just fine here with Elementor …

Ok, so:
Elementor adds lots and lots of surrounding elements to the orderpage widget (about a dozen or more)
Interestingly, after payment (i.e on the so-called “thankyou page”) it does not add those wrapper elements anymore.
Why ? I have no idea.
That said – given the popularity of elementor – I’ll have a look as to whether it’s something they should perhaps be doing or I should perhaps be doing and/or find a workaround/fix if applicable. I simply do not know yet where the issue is exactly
so will probably not be something that can be done quickly as it may have many implications elsewhere.

That said, if the only page where you are having issues is your thank you page, there is certainly an easy fix by simply adding the following (adjust as required) to your css somewhere (see https://docs.wp-pizza.com/advanced/?section=frontend-css-styles-layout). This is a very specific override to that widget there so should be quite safe to use

.wppizza-order-wrap-thankyoupage{
padding-top: 100px;
margin: 0 20%;
}

PS: if you enable debug on your site you will see that elementor throws lots and lots of database errors. which may – or may not – be related. Just mentioning it though that really is something for them to fix.

That’s it from me for now on this subject

>but the provider removed it from the portfolio years ago and because of all the PHP updates
Sorry, but I do not understand that statement. Could you expand on that ? what provider removed what exactly ? I am also somewhat puzzled as to what you mean by you can only use it on “outdated php versions “. wppizza is being developed with latest php (and with even not yet marked as stable future / development php versions)

>delivered with WooCoomerce
I don’t follow. WPPizza has nothing to do with woocommerce ?!

Other than that you might also find that 3.19.2 will fix your thank you page issue.
(As it happens, when dealing with something else a few days ago, I stumbled across a different way to implement the thank you page output which I believe works around all these potential theme and page builder incompatibilities.)

In any event, it is of course entirely your choice to switch to woocommerce if you so wish .

>Was referring to my old theme…
Ok, thanks for the clarification.

>Almost every commercial theme…
It’s not actually themes themeselves – or indeed woocommerce – that were the issue, but elementor (as you know of course)
but I’ll spare you the details as it’s quite irrelevant now

>Oh my God…that fixed the problem!
Glad to hear it

>I spent hours trying to solve it somehow and you have fixed it now
Only possible because you provided the info and details I asked for . So you can thank yourself too 😉

Don’t cry. It’s almost xmas. Time to rejoice and all that and if you have any more / other issues, get in touch. I cannot fix or amend things if I know nothing about them

Cheers
