i also noticed that you have a rogue " /> on your site at line 4 which can cause all sorts of issues (not necessarily regarding paypal, but you might want to fix that regardless)

for wppizza v3, the gateway logging has been made global and moved to
/wp-admin/edit.php?post_type=wppizza&page=settings
to log all these files in the same place, wppizza/logs

so first question is:
are there any paypal related logs in that directory (wp-content/plugins/wppizza/logs/)?
did you receive any notices/emails to your admin email regarding paypal errors of some sort ?

that said, if you dont receive any IPN notifications in the first place , there’s nothing to log as it never reaches the server.
can you show a screenshot of the ipn order history of your paypal account ?
do those notifications say “sent” or do they say something else ?

and how is that a “vague place” anyway? it is specifically written for the wppizza paypal plugin

what are you talking about ?
do you want me to copy and paste what it says in the troubleshooting section ?
i cannot possibly do any of this for you as i have no access to your server nor to your paypal account
once you give me some sort of information as asked there , i might be able to help further

secondly, you have not even provided the most basic info like a link to your site
do you want me to guess what version(s) you are running or plugins you are using ?

furthermore, from what i can see i replied to absolutely all emails (not only yesterday , but going back months and years)
checked your spam folder ? what email did you send it to ? what’s the subject line so i can search for it , in the unlikely case i overlooked this

i cannot see any topics that are in the moderation queue either

you have either not setup IPN or IPN is not working
