Error with WooCommerce PDF Invoices

Hello @emoteek

You are having this issue when you enable our PDF plugin or Ultimate Member?

When I enable your PDF plugin ??

What happens if you disable the Ultimate Member plugin?

After deactivating ultimate Members it happens that the problem is the same

The error messages is exactly the same

our plugin does not use the function amp_is_available(), so something else on your site must be calling it (during the creation of PDF invoices). Could you try deactivating plugins one by one to see which plugin is responsible? We can then look closer into the issue to see if it’s a conflict we can resolve from our end or if it needs to be resolved by the other party.

Hi, I tried to deactivate my plugins but the problem is removed when I deactivate your plugin only.

Also I tried to delete another plugin while having yours activated and another error occured : échec de la suppression : Notice: Undefined index: name in /wordpress/core/5.7.1/wp-includes/class-wp-roles.php on line 291 Notice: Undefined index: name in /wordpress/core/5.7.1/wp-includes/class-wp-roles.php on line 291 Notice: Undefined index: name in /srv/htdocs/wp-content/plugins/ultimate-member/includes/core/class-roles-capabilities.php on line 113 Notice: Undefined index: name in /srv/htdocs/wp-content/plugins/ultimate-member/includes/core/class-roles-capabilities.php on line 113 {"success":true,"data":{"delete":"plugin","slug":"polylang","plugin":"polylang\/polylang.php","pluginName":"Polylang"}}

Also, when your plugin is active and that I deactivate then activate another plugin I have this error message : Cette extension a généré 394 caractères de sortie inattendus lors de son activation. Si vous remarquez des messages ? headers already sent ?, des problèmes avec vos flux de syndication ou d’autres soucis, essayez de désactiver ou de supprimer cette extension.

Hi @emoteek

The errors you are seeing are related to the Ultimate Member plugin, maybe some capabilities issues there for the current user role? I’m a bit confused how you could receive the same errors with that plugin disabled, because they can only occur when the plugin is enabled, maybe was previous ones?

In your second message you are pointing an issue with our plugin disabled, so not relation at all with it.

Hi, I open this conversation once again after contacting the support from Ultimate Members, here is their answer after checking the problem ( I gave them an admin access + DB access etc ) ->

“It looks like the issue with the message on your pages was actually being caused by woocommerce-pdf-invoices-packing-slips plugin.
We’ve deactivated that plugin for now and we’ve run a full sync. I can see that error message is gone now. You’ll want to let the plugin devs know the issue was with that plugin.”

@emoteek I suspect that you may have enabled the “Enable debug output” option of our plugin in the Status tab, which will show ALL errors from your site (from ALL plugins) that would normally be surpressed. This means that enabling our plugin doesn’t cause those errors, but simply shows them.
Can you check this? This option is only meant for debugging and shouldn’t be activated on a live site.

Yes it seems that it is activated..

However those messages aren’t showing any critical error so I should let it be and just deactivate the debug output?

well, it would be a good idea to follow up on those errors with the plugins that throw them, for example the ones coming from Ultimate Members which are errors in their plugin code (you never know how it could affect your processes and those type of errors are easy to fix).

But yes, besides that you can certainly deactivate the option. It is meant for debugging purposes only.

Glad we have solved the mystery!

Yes thanks for your help ??
