PHP Errors from wpml-config-class.php

Overview of the Issue

Catchable fatal error: Object of class stdClass could not be converted to string in /home/lahjatup/public_html/markkinointiopisto.fi/wp-content/plugins/sitepress-multilingual-cms/inc/wpml-config/wpml-config.class.php on line 252

Or

Warning: dirname() expects parameter 1 to be string, object given in /home1/treasure/public_html/dev/wp-content/plugins/sitepress-multilingual-cms/inc/wpml-config/wpml-config.class.php on line 252

The above PHP errors will appear in your Admin pages like your plugins, theme or Translation Management → Multilingual Content Setup pages.

Workaround

1. Login via FTP
2. Locate the sitepress-multilingual-cms/inc/wpml-config/wpml-config.class.php file
3. Locate the line mentioned in the PHP error you see (252). For example:

   $type = ( dirname( $file ) == get_template_directory() || dirname( $file ) == get_stylesheet_directory() ) ? 'theme' : 'plugin';
   $admin_text_context = basename( dirname( $file ) );

4. Delete both lines of code
5. In the same file locate the following code (around line 210):

   }else{
    $config = icl_xml2array( file_get_contents( $file ) );
   }

6. Modify this block of code to become:

   }else{
   $config = icl_xml2array( file_get_contents( $file ) );
   $type = ( dirname( $file ) == get_template_directory() || dirname( $file ) == get_stylesheet_directory() ) ? 'theme' : 'plugin';
   $admin_text_context = basename( dirname( $file ) );
   }

7. Save the file and upload to your server
