Hello Incomedia, all,

I found a new error log into the user defined directory !!

We can / need to create this user defined directory if you are using the rates & comments object to register the user votes....

But for Paypal paiment this directory is not specified into the documentation and seems not mandatory, and the paypal works without this directory (or may be I do an error).

The user defined directory is configured here.

And the poor documentation on this directory, said (sorry in French).

" ▪ Dossier du serveur avec l'accès en écriture  : dans ce champ il est nécessaire de préciser le chemin sur le Serveur du dossier avec accès en écriture, à savoir du dossier dans lequel est possible l'écriture du code PHP.

Habituellement les fournisseurs d'accès Internet permettent l'accès en écriture pour chaque dossier du serveur: dans ce cas, il n'est pas nécessaire de renseigner un chemin pour le dossier public. Au contraire, pour connaître le chemin complet du dossier public, il est nécessaire de contacter son fournisseur d'accès Internet.

À travers la section WebSite Test du Panneau de Contrôle en ligne il est possible de vérifier si le dossier avec accès en écriture spécifié, et si les éventuels sous dossiers contenus, existent et, dans ce cas, s'ils permettent réellement l'écriture des données. »

"

So what the real usage of this directory and what are the files written here. If you are using the votes & comments object, OK you will have a random file like F67272988 where your comments and votes are registered. 

But so what for other(s)  ????

I found that paypal errors could be here. The file is spelled paypal-error.log And seems created when you got some payment errors from a customer.

The content of this file is like:

[2022-01-04 10:33:34]

{"href":"https:\/\/api.paypal.com\/v2\/checkout\/orders\/1T153876XX500314G","rel":"self","method":"GET"}]}

So my question are:

Does other files can be founded into this directory. When the documentation said 'possible to write with PHP code' it is very light explanation... or NOT an explanation.

Who writes the paypal-error.log file here. incomedia or Paypal... I suppose that is Incomedia because the payment is not done... and Paypal server has no knowledge of this directory to write into !! 

So what is the explanation of this content file... If this file is created we can suppose that it is to help the webmaster. So please with my logs here who can explain why a paypal error occurs...

NOT_ELIGIBLE ??? wo what does it mean ?

Incomedia it coul be very nice to have a clear explanation of this error contents to help us...
Write a file into a directory if it is not useful, so what the usage !!!!

Thanks for clarification and to take this request to improve documentation about that.

Asked since long time, why not create a troubleshooting guide where errors are fully documented and explanations are done to solve them.
Everyone will win time, us and you by less support on documented errors and solutions.

Enjoy!
