The following deprecation notices are reported on PHP8+:

Deprecated: Optional parameter $search declared before required parameter $table is implicitly treated as a required parameter in /home/nglcom/public_html/negoluz.nz/wp-content/plugins/search-and-replace/inc/Database/Exporter.php on line 295

Deprecated: Optional parameter $replace declared before required parameter $table is implicitly treated as a required parameter in /home/nglcom/public_html/negoluz.nz/wp-content/plugins/search-and-replace/inc/Database/Exporter.php on line 295

There is no impact on the behavior, apart from adding deprecation notices.
