 * Hello,
 * I would like to inform the plugin’s creator that having a single language in 
   the general languages settings causes multiple warnings while saving post/page.
 * Here are some examples:
 * Warning: Invalid argument supplied for foreach() in plugins/polylang/include/
   admin-filters.php on line 387
    >>> foreach ($_POST[‘post_tr_lang’] as $lang=>
   $tr_id)
 * Warning: Invalid argument supplied for foreach() in /home/ahavaves/public_html/
   wp-content/plugins/polylang/include/admin-filters.php on line 393
    >>> foreach(
   $translations as $lang=>$tr_id) {
 * It was detected in WP3.3.1 and Polylang 0.7pre14.
 * In most (if not all) cases there will be more than one language, in addition,
   creating a second language (even if it is not used for now) will solve the problem
   and can be considered as a workaround here.
 * Goodluck!

 * Thank you for the bug report. I will look at this to be cleaner…
 * Please keep the ‘polylang’ tag as is, as I receive by email all topics linked
   to this tag. Of course, you can add other tags if you want.

 * I am currently working on this bug. Although I perfectly understand what’s wrong
   in Polylang’s code and so will correct it, I did not succeed to display these
   warnings on my test site without modifying the code. I guess that these warnings
   are sent before WordPress redirection occurs and so I don’t see them. So I am
   curious to know in which circumstances you got these warnings. Knowing this could
   help me detecting other similar bugs.

 * I haven’t done something special other than running WP3.3.1 with Network (MultiSite),
   installed Polylang plugin, configured single Language, and tried to publish/update
   a post/page (in that order).
 * I assume the ‘Network/Multisite’ might be the difference here 🙂
    If you haven’t
   tried recreating it on a ‘Network/Multisite’ then I would suggest to try and 
   see the results…
