SportsPress Conflict: unable to save CPT’s in selected language

In addition to the above and maybe helpful: in the example of a ‘Calendar’ post type, in the ‘Details’ section (with dates, league, season, etc.) Polylang adds a section called ‘Language’ (sp_calendar-language-field). Underneath is a select input to choose a language. I wonder why that is needed, when the main setting of the post is already set to a language.

Furthermore under the Language section is another – without a heading – called ‘sp_calendar-post_translations-field’ with initially a link “+ Add New Tag”. I also wonder why that is there.

Can someone please look into this very annoying problem which makes Polylang unusable with SportsPress. I’m about to give up and switch over to WPML.

OK, one more additional clarification, which I think might be the reason it goes wrong and is maybe not related to this plug-in but to SportsPress.

The ‘Details’ section has a php function to include CPT-depending input fields, they are called with

<?php
	foreach ( $taxonomies as $taxonomy ) {
	sp_taxonomy_field( $taxonomy, $post, true );
	}
?>

When I remove this, the ‘Language’ heading and inputs disappear, along with of course all the other (needed) inputs like ‘League’, ‘Season’, etc. But I can edit and save now normally, without a strange language number added.

Right, found the culprit but I’m not sure whether Polylang should prevent being included with the above ‘foreach’ or whether SportsPress should change the call for taxonomies to exclude Polylang’s. I will post this problem on their support thread, too.

I have posted this problem on the SportsPress support, too. And I seem to have found a solution which is not related to Polylang but indeed to SportsPress. Unless when you check my solution and think: “Oh wait, we can prevent that from happening”. If that’s the case, please let me know.

On the SportsPress support forum linked above, they are not sure whether the conflict is caused by their plug-in or by Polylang.

Is anyone on the dev team here ( @chouby @manooweb @raaaahman ) even interested in this problem?

The latest version brings no solution. Instead, it’s even worse. When now trying to Update I get:

Warning: array_flip(): Can only flip STRING and INTEGER values! in **********\wp-content\plugins\polylang\include\translated-object.php on line 258

and:

Warning: Cannot modify header information - headers already sent by (output started at **********\wp-content\plugins\polylang\include\translated-object.php:258)

When going to ‘Languages’ the same warning as above is displayed. A new language is now added without any value (so empty) and I’m unable to delete it.

Right, on top of getting no support here whatsoever, it’s getting worse and worse which makes me now switching to WPML and saying goodbye to Polylang forever.
