I only have read permission to my files but I need write permission, I think

This may be a question for your hosting provider because the permissions scheme for a server can vary depending on several things.

If the application (WordPress) cannot create a directory (this is unusual) then you need to create it manually and yes, it needs to be writable, but so do any of the other directories in the wp-content/uploads/ directory.

What you should do is check the permissions for other directories in wp-content/uploads/ and create the new directory with the same permissions. For most servers, this will be 744. Do not try to use 777, this will break things.

I have the same problem. However I deliberately won’t let “plugins” directory to be written by the server. If a plugin needs to write something, it should write it to the “uploads” directory. It works for all other plugins and themes except for this one. You should consider writing service-worker.js in the uploads directory and serve it from there.

Also Wordfence and other scanners issue warnings if the files in the plugin directory are different from the ones in the repository.

Meanwhile, how can I simply disable this feature and thus not get push notifications I don’t need anyway?

Participants Database does not attempt to write to the plugins directory. With the default configuration, it only writes to the uploads directory, so you should be good.

Thank’s for your answer and help!

That’s not how it looks:

PHP message: PHP Warning:  fopen({...}/wp-content/plugins/mailin/js/service-worker.js): failed to open stream: Permission denied in {...}/wp-content/plugins/mailin/sendinblue.php on line 647

This error stopped when I switched “Activate Marketing Automation through Brevo” to “No”

That is referring to read access, I thought we were talking about write access.

I don’t understand how this is related to the Participants Database plugin.

Sorry. I probably miss understood the thread. However, it is about write access. Here’s the context

 $service_worker_file   = str_contains($site_url, self::URL_CHECK_STAGING)
                    ? self::PUSHOWL_STAGING_URL
                    : self::PUSHOWL_PRODUCTION_URL;
                $js_content            = "importScripts('" . $service_worker_file . "');";
                $service_worker_script = fopen($service_worker, "wb");
                fwrite($service_worker_script, $js_content);
                fclose($service_worker_script);

Where $service_worker is

const SERVICE_WORKER_FILE_URL = "/js/service-worker.js";

$service_worker = __DIR__ . self::SERVICE_WORKER_FILE_URL;
 if ( ! file_exists($service_worker)) {
      self::install_service_worker_script($service_worker);
 }

So obviously the plugin is trying to write to the file wp-content/plugins/mailin/js/service-worker.js

And that’s what’s written

const PUSHOWL_PRODUCTION_URL = "https://cdn.pushowl.com/latest/sdks/service-worker.js";

OK, but the plugin referred to in that call is named “mailin”, so not Participants Database.

OMG, sorry. I messed up big time. I was looking for support for Brevo plugin and I made a search that included something about permissions, and this was in the results. I was sure the results were for the Brevo plugin, so I didn’t even check. Must have been late. Sorry!
