 * I’ve been using acf pro and found the extention plugin, so just hit the download
   button of that and installed it to my website.
 * But it shows some error messages such as,
 * Fatal error: Uncaught Error: Call to undefined function acf_esc_attrs() in /xxxxx/
   xxx/xxxx/site-name/app/public/wp-content/plugins/acf-extended/includes/acfe-field-
   group-functions.php on line _412_
 * I have no clue how to fix that.

 * Hello,
 * Thanks for the feedback!
 * Which version of ACF Pro are you using?
 * The error you posted says your ACF Pro is missing the `acf_esc_attrs()` function.
   I checked the code source, and it says that this function appeared in ACF Pro
   5.8.1, so I would recommend to use at least this version.
 * I’ll update this function usage in ACF Extended to use an older version `acf_esc_atts()`
   instead, in order to comply with the ACF Extended requirement which says it needs
   ACF Pro 5.8.
 * Note that I’ll bump this requirement to ACF 5.9 minimum in a future update (ACF
   5.8 is 4 years old now). So it’s really better if you use a newer version of 
   ACF anyway.
 * Hope it helps!
 * Have a nice day!
 * Regards.
