[Plugin: Subscribe2] Error: 'Warning: implode() [function.implode]'

@Brunzo,

Okay, so the server is the same, but Subscribe2 code is the same also. If it works on one but not another, as you rightly point out, something must be different. You tell me?

Are you using exactly the same theme and set of plugins on the 2 sites? Are you sure the PHP configuration is identical? (php.ini files can be domain specific).

as I’ve said above, until I have steps to re-produce the error I cannot being to fix it as I can’t guess where the issue might be coming from.

@mattyrob,
Yes, that makes sense, and it is weird!

I have:
-Same plugin set
-same php.ini
-same configuration
-same template

Is there any debug or test that would be helpful to understand why this is happening?

thanks.

@Brunzo,

There is no debug code but if you are happy playing with code you can run some tests.

Find line 543 in the class-s2-core.php file; it should be like this:

$this->post_cat_names = implode(', ', wp_get_object_terms($post->ID, $s2_taxonomies, array('fields' => 'names')));
$this->post_tag_names = implode(', ', wp_get_post_tags($post->ID, array('fields' => 'names')));

Before that break the code in those lines down to see if we can isolate the issue. Something like:
`var_dump(wp_get_object_terms($post->ID, $s2_taxonomies, array(‘fields’ => ‘names’)));

That should return an array, if it doesn’t then the next step is to figure out why WordPress thinks your post has no category names attached to it.

@mattyrob,
I tried the code mentioned above but I got no luck.

Are you available to work on this?
I’m ok either donate or pay you for the time you spend on this.

Thanks.

@Brunzo,

If you are happy to and can give me access to you site (WordPress, cPanel, PHPMyAdmin etc) then I’ll take a look. Contact me via here.

For info, though the error message persists when I do a test send, the plugin has started working again! Users are getting updates! Wish I know what I did…basically I reset the config and then re-edited for our needs. In any case, it worked!

Hello,
@mattyrob

I have the same error
Warning: implode() [function.implode]: Invalid arguments passed in /home/content/xxx/html/wp-content/plugins/subscribe2/…

My intuition is wp cache plug in.
When de activated, my mails are leaving otherwise nothing happens.
if it can helps..

bye

@julian99,

I was doing some paid work for a client with several WordPress issues when this one cropped up on his site. I was able to fully debug it there and have patched it in the Subscribe2 code. It will be fixed in 8.3 but if you can’t wait until then use the development code.
