 * Hello,
    I am very happy to find this plugin but after I believe configuring it
   correctly (test connection works from wp admin), I am getting the fatal error
   below when trying to use it to login:
 * PHP Fatal error: Cannot redeclare exlog_modify_repeater_item_data_for_view_use()(
   previously declared in /home/site/public_html/wp-content/plugins/external-login/
   options/wpconfig_options.php:24) in /home/site/public_html/wp-content/plugins/
   external-login/options/wpconfig_options.php on line 24

 * Hey [@xprojectsx](https://wordpress.org/support/users/xprojectsx/),
 * I can’t replicate this straight away. Can you confirm which version of PHP you
   are running?
 * My theory at the moment (just a guess) is that you are using a version of PHP
   older than the plugin currently supports and it doesn’t like the way I’ve nested
   a function in a function.
 *     ```
       function exlog_modify_repeater_data_for_view_use($repeater_data) {
           function exlog_modify_repeater_item_data_for_view_use($repeater_data) {
               $formatted_data = array();
               if (is_array($repeater_data)) {
                   foreach ($repeater_data as $repeater_item_data) {
                       $formatted_repeater_items_data = array();
                       foreach ($repeater_item_data as $repeater_item_datum) {
                           if ($repeater_item_datum['repeater_field']) {
                               $value = exlog_modify_repeater_item_data_for_view_use($repeater_item_datum['value']);
                           } else {
                               $value = $repeater_item_datum['value'];
                           }
                           $formatted_repeater_items_data[$repeater_item_datum['name']] = $value;
                       }
                       array_push($formatted_data, $formatted_repeater_items_data);
                   }
                   return $formatted_data;
               } else {
                   return $repeater_data;
               }
           }
   
           return exlog_modify_repeater_item_data_for_view_use($repeater_data);
       }
       ```
   
 * I am guessing each time `exlog_modify_repeater_data_for_view_use()` is run it
   is trying to redeclare `exlog_modify_repeater_item_data_for_view_use()`.
 * The issue is in the following file:
    /wp-content/plugins/external-login/options/
   wpconfig_options.php
 * If your able to, you could test if this theory is correct by modifying the code
   to this:
 *     ```
       function exlog_modify_repeater_item_data_for_view_use($repeater_data) {
           $formatted_data = array();
           if (is_array($repeater_data)) {
               foreach ($repeater_data as $repeater_item_data) {
                   $formatted_repeater_items_data = array();
                   foreach ($repeater_item_data as $repeater_item_datum) {
                       if ($repeater_item_datum['repeater_field']) {
                           $value = exlog_modify_repeater_item_data_for_view_use($repeater_item_datum['value']);
                       } else {
                           $value = $repeater_item_datum['value'];
                       }
                       $formatted_repeater_items_data[$repeater_item_datum['name']] = $value;
                   }
                   array_push($formatted_data, $formatted_repeater_items_data);
               }
               return $formatted_data;
           } else {
               return $repeater_data;
           }
       }
   
       function exlog_modify_repeater_data_for_view_use($repeater_data) {
           return exlog_modify_repeater_item_data_for_view_use($repeater_data);
       }
       ```
   
 * If you could still let me know which version of PHP or even better, if you’re
   running a lower version than the currently supported “5.6.34 or higher” to up
   your version.
 * Thanks,
 * Tom

 * Thank you for the quick reply. First, updating the code worked! To answer your
   question, I was running 5.6. I updated it to 7.2 but that did not resolve the
   issue even after restarting apache and emptying cache. When I updated the code
   then it worked.
 * Thank you very much.

 * Hey Paul,
 * Thanks for the details. It’s really helpful.
 * I’ll try and refactor this code ASAP and push an update.
 * I’ll leave this ticket open until a fix is deployed.
 * I saw you’ve written another couple of support questions and I’ll try and get
   to those as soon as I can.
 * Thanks,
 * Tom
