Title: Fix qTranslate with WordPress 3.9 Author: Alex Kirk Published: April 17, 2014 Last modified: December 1, 2016 --- # Fix qTranslate with WordPress 3.9 April 17, 2014 When updating a blog of mine to WordPress 3.9 the page wouldn’t load anymore because of [qTranslate](http://www.qianqin.de/qtranslate/) not able to cope with the update. In the error log it says: `PHP Catchable fatal error: Object of class WP_Post could not be converted to string in ../wp-content/plugins/qtranslate/qtranslate_core.php on line 455 The error is caused by this change: [get_the_date() to accept optional $post argument](https://core.trac.wordpress.org/ticket/13771) There is [a proposed quick fix](http://zioproto.ninux.org/wordpress/2014/04/17/dirty-and-quick-fix-for-qtranslate-plugin-on-wordpress-3-9/) by [Saverio Proto](http://zioproto.ninux.org/), but it doesn’t take the problem at its root: qTranslate registers the function qtrans_dateFromPostForCurrentLanguage($old_date, $format ='', $before = '', $after = '') for the hook get_the_date but it actually [only accepts one parameter](http://codex.wordpress.org/Function_Reference/get_the_date). With the new update it accepts a second parameter $post, which now wrongly fills the variable $before that is in the process being converted to a string. So [the solution](https://gist.githubusercontent.com/akirk/10979790/raw/3b2b37b399a82dc82723fb6b8e703c1d981b26f9/qtranslate_core.php.diff) simply is to delete the two parameters that were assigned the wrong meaning and have defaults anyway.

Nothing spectacular, just ahead of the line with the error message I added a ` var_dump($before);` to see that the content of the variable is an object instead of a string, then I checked the [Codex](http://codex.wordpress.org/Function_Reference/get_the_date) to see the parameters of the function being called. 5.

I´m pretty new to WordPress and especially to working with github. So my question is: Is it correct to download the gist code you offered, then extract the file in it and upload it on my FTP to the qtranslate folder? This is what I did, but I still get the error message on my website like before: CATCHABLE FATAL ERROR: OBJECT OF CLASS WP_POST COULD NOT BE CONVERTED TO STRING IN /HOME/. SITES/698/SITE8704257/WEB/WP-CONTENT/PLUGINS/QTRANSLATE/QTRANSLATE_CORE.PHP ON LINE 455 10. What am I doing wrong? 11.

Either you can use the program called` patch` or, as this is a quite simple change, simply do what is shown using a text editor: remove the red line and add the green line (or just modify the line so that it looks like the green line afterwards). e.

Good that you also explained the root cause. I’m still wondering why the $before and $after are added to the function parameters and not outside of it? 17.

The function `qtrans_dateFromPostForCurrentLanguage` provides a $before and $after parameter when the WordPress API doesn’t ask it to provide it. When WordPress changed their API by adding parameters, the $before variable now gets some unexpected content (which previously always was an empty string, because of the default value `$before = ''`) 22.

For all other problems it might be worth trying to switch to [mqtranslate](http://wordpress.org/plugins/mqtranslate/), a more actively maintained qtranslate fork. e.
