So they are loading their own(old) jquery alongside the WP jquery in no conflict mode.
Though in principle that’s ok i guess, in my book that’s still a ridiculously stupid idea.

In any event, I just downloaded and installed their blank/default theme and the text shows up just fine, so I can only guess it’s some customisation or some other plugins that cause the issue,

So I would suggest to do the following to narrow it down.
a) disable all other plugins and see if it works then and re-enable one by one to see which one causes the problem
b) try a default theme (2016 for example) and see if it works there – maybe there are some customisations in the theme somewhere…

>I assume the older jquery is a leftover from or loaded by another plugin.
looks to me more like it’s your theme, but i cannot tell .

>How do I remove it or prevent it from loading?
remove the plugin that loads it or get it fixed by the plugin developer and if it’s the theme remove it / fix it there

ok.
i’ll check in out in more detail tomorrow.(kind of late here)

>The problem was that AOL does not accept mails that are not send from an AOL account but have a reply to an AOL account in their header.

i am highly suspicious of that statement.

” AOL does not accept mails that are not send from an AOL account” …..really ? AOL only sends to itself ?

although I do not know your setup – and might of course be completely wrong – my guess would be your from address is not set up to be from your server and/or does not exists (that big red DMARC notice unless you turned it off)

but then again, maybe AOL are really that dumb these days..

>I just ereased these line in wppizza.send-emails.inc.php and it works
and you will never be able to upgrade/update again.
this (editing corefiles) is definitely the wrong way to do things and it cannot possible be right to not allowing a reply to address…..

anyway, just my 2 cents. you can do as you wish of course

> I’ve worked with filters and such before, just never with WP Pizza,
this has nothing to do with wppizza . filters work the same everywhere. wppizza or not.

>and I’m not finding any documentation that helps me do what I’m trying to do

I gave you all you need.
the subject line is made up of three parts. all of which are filterable . (and the parameters passed to the filter in the file i mentioned near the beginning of this topic should be self-explanatory)

i must admit, I do not know what more info it is you are looking for really.

you use filters to change what they return.
the subject line is made out of 3 parts (as mentioned) filterable by those 3 filters

there’s no inbuilt way as such, but if you want, you could use the hidden input elements that have the class wppizza_order_transaction_id and add classes that display your icon (via jQuery I would have thought) where the value of that hidden element has “COD” in it – or something along these lines anyway

>But plugin still show old user post code 1000

unless you are caching the order page, this is simply not possible.

but once you have set it/changed it , the session is set and it will keep whatever you have done previously. i.e your session data takes precedence over the profile data once it is set
