 * I have an issue with plugin.
    While editing page with this custom field all values
   are deleted when i click Update and it displays:
 * Warning: urlencode() expects parameter 1 to be string, array given in /usr/home/../../
   public_html/wp-content/plugins/advanced-custom-fields-table-field/acf-table-v5.
   php on line 165
 * Any ideas?

 * This is a strange warning because, the `urlencode()` function contains another
   function called `json_encode()` that is definitely returning a string and never
   an array `urlencode( json_encode( $data_field ) )`. This function is also on 
   line 169 and not 165. So the answers of the following two questions may help 
   me.
 * Do you have the current version of the plugin?
    Is your PHP version greater than
   or equal 5.2.0?
 * Thanks, Johann

 * I could not replicate that issue. Is it still exists? May can you provide more
   details like a screenshot of the table editor?
 * I try a fix by changing that json_encode() function that returned an array with
   the WordPress equivalent wp_json_encode() in the next release.

 * Yes, it is still exists. After typing datas to table and click Update i have 
   this → [http://prntscr.com/7235q4](http://prntscr.com/7235q4) and empty table.

 * I just released a new version of the plugin. If we are lucky this may solve your
   problem.

 * Thanks, but no way! Now i have:
 * `Notice: Undefined index: use_header in /usr/home/pm/domains/bros.pm.usermd.net/
   public_html/wp-content/plugins/advanced-custom-fields-table-field/acf-table-v5.

 * I think, this is an unique problem and I only can research it on the website 
   the issue exists.
