Too few arguments to function plgContactenhancedCustomcode::onValidateContact(), 2 passed in /var/www/vhosts/--domain-redacted--/httpdocs/libraries/src/Plugin/CMSPlugin.php on line 284 and exactly 3 expected

Dear blue_Shift,

I have just checked and the onValidateContact() for Joomla 4 only accepts 2 arguments.

I believe I know what's happening. You used to subscribe to CE PRO, which includes the Contact Enhanced > Custom Code plugin and you've updated using the CE PLUS, which doesn't include this plugin. That's why you are getting this error.

I'm not sure which script you are running when we trigger the onValidateContact(), but you can check it in the Plugin Options.

You have two options:
1. Disable or uninstall the Contact Enhanced > Custom Code plugin
2. Upgrade to Contact Enhanced PRO.

Best regards,

That site was not using any custom code, anyway. but the multiple file uploads is now giving us "Joomla\CMS\Filesystem\Folder::create: Path not in open_basedir paths" (I had to manually create the uploadedfiles folder in the default location)

Is this related to the Fail2Ban incompatibility you mention in your documentation?

I don't think this is related to Fail2Ban, but you are welcome to check if your hosting provider uses Fail2ban.
open_basedir PHP directive defaults to allow all directories. You can check your server's open_basedir by going to System >
System Information > PHP Information and search for open_basedir.

A possible solution is to enable the FTP layer from System > Global Configuration > Server tab > FTP Settings. Add FTP details (host, username, and password) for a user with access to your server.

I'm not able to test it myself because I can't reproduce the error, but by enabling the FTP layer Joomla should be able to overcome this server's limitations.

Let me know if you need any further assistance.

It's our own server and it IS running Fail2Ban.

It appears we can specifically permission that folder in open_basdir

Better image showing other folder(se) in open_basedir

Dear blue_shift,

Apparently, Joomla should have access to the entire webspace root, so it should work.
Did you try the FTP Layer?

Best regards,

I couldn't see a way to add FTP layer post hoc in Joomla 4, so we relocated the uploads folder to the root (with a weird name) so we could permission specifically without getting too deep into the site. It's working now.
