 * Please update lines 476, 477, and 528, 529 so that the following PHP warning 
   is not triggered:
   “Trying to access array offset on value of type null in …/plugins/
   hitsteps-visitor-manager/init.gravityform.php”Please see this discussion for 
   an explanation of the issue:
 * [https://stackoverflow.com/questions/59336951/message-trying-to-access-array-offset-on-value-of-type-null](https://stackoverflow.com/questions/59336951/message-trying-to-access-array-offset-on-value-of-type-null)
 * The parent array $_hs_uid_data_cache needs to validated (in addition to the actual
   value of the array that is already checked with !isset($_hs_uid_data_cache[round(
   $_POST[`'_hs_uid_data`'])])) )
 * > This happens because `$cOTLdata` is null. Previous versions of PHP may have
   > been less strict on such mistakes and silently swallowed the error / notice
   > while 7.4 does not do this anymore.
   > To check whether `$cOTLdata` is null use [is_null()](https://www.php.net/is_null):
   >     ```wp-block-code
   >     is_null($cOTLdata)
   >     ```
   > 
   > Which means the line should look something like this:
   >     ```wp-block-code
   >     $len = is_null($cOTLdata) ? 0 : count($cOTLdata['char_data']);
   >     ```
   > 
   > However, in case both `$cOTLdata` and `$cOTLdata['char_data']` could not exist,
   > you can use `isset()` for both at once:
   >     ```wp-block-code
   >     $len = !isset($cOTLdata['char_data']) ? 0 : count($cOTLdata['char_data']);
   >     ```
