Uncaught InvalidArgumentException: Missing "qtranslate-edit-language" field in $_REQUEST!

[bagaweb]

I cannot understand why but I receive this error when trying to publish a new page with 3.7.1.

Un errore di E_ERROR è stato causato nella linea 206 del file /home/public_html/wp-content/plugins/qtranslate-xt/admin/qtx_admin_utils.php. Messaggio di errore: Uncaught InvalidArgumentException: Missing "qtranslate-edit-language" field in $_REQUEST! in /home/public_html/wp-content/plugins/qtranslate-xt/admin/qtx_admin_utils.php:206

Had to revert to 3.6.3 to be able to publish without errors.

Yes this is something new i've added to clearly detect invalid post requests. Here you have some qtranslate-fields in your request, but the language that should be given by qtranslate-edit-language is missing. This comes from the submitted form and it should never happen! So the exception is a security belt. Before, the language was sent in the admin edit cookie but i removed that one in 3.7.0 (there were several reasons for that).

Can you better detail the context of your post request?

[herrvigg]

Which edit mode are you using: LSB, RAW or single language?

[herrvigg]

@bagaweb I've tried this again and it works fine with all modes (anyway this should not concern the raw mode). FYI the hidden field qtranslate-edit-language is created dynamically client-side in javascript when the hooks are added so check that you don't have a JS error in the browser console. If the hidden field is created correctly it should be transmitted with the form normally when you submit the page.

I was editing in LSB mode. I tried to reproduce the problem on a localhost installation but everything works fine. I need to try again on the live site and check the browser console.

[herrvigg]

Not sure what happened but i believe this is working fine. If there is a specific case please provide more info so we can reproduce it.

@bagaweb sorry for digging but I've approached the same issue with a recent version of this plugin. What might cause it? I'm receiving it when trying to add any changes into menu view (newest Wordpress and newest Qtranslate_XT installed)

[bagaweb]

@pawelskaba I cannot remember what was causing this problem, it was too long ago, sorry.

The problem exists when i edit a admin CPT post. For this CPT i had disabled the translation option in QTranslate settings Menu - (Languages -> Advanced tab - i had disable For this cpt).
I modified the cpt post edit form for my need so i include this line:

And on save post the problem gone. :)
OR if you enable translation for this CPT all works ok!
