[BUG] A data query is issued instead of the blocked message

[konsti2020]

Describe the bug From time to time I test my homepage to see if everything is working. Today Zero Spam had some unexpected behaviour. I tried to register myself with a blocked domain but instead of showing the Blocking page it showed what to me looks like a data request for some sort of API or PHP error message. The output text after clicking on register: Array ( [headers] => Requests_Utility_CaseInsensitiveDictionary Object ( [data:protected] => Array ( [server] => nginx [date] => Sat, 08 Oct 2022 12:55:47 GMT [content-type] => application/json; charset=UTF-8 [vary] => Accept-Encoding [x-robots-tag] => noindex [link] => ; rel="https://api.w.org/" [x-content-type-options] => nosniff [access-control-expose-headers] => X-WP-Total, X-WP-TotalPages, Link [access-control-allow-headers] => Authorization, X-WP-Nonce, Content-Disposition, Content-MD5, Content-Type [allow] => POST [x-httpd-modphp] => 1 [x-cdn-c] => static [content-encoding] => gzip [x-sg-cdn] => 1 [x-proxy-cache-info] => DT:1 [host-header] => 8441280b0c3****98a563a7 ) ) [body] => Warning: json_decode() expects parameter 1 to be string, array given in //www/zerospam.org/public_html/wp-content/plugins/zero-spam-store/core/class-api.php on line 182 {"status":200,"response":"success","body_response":{"report_type":"email_address","report_module":"registration","report_failed":"blocked_email_domain","email_details":{"names":["inspector",""]},"report_key":"[email protected]","reporter_email":"**my_mail@.de","app_key":"my_page","app_type":"wordpress","app_details":{"app_version":"6.0.2","app_type_version":"5.4.3","app_language":"de-de","app_email":"my_mail","app_name":"page_title","app_desc":"page_subheader"},"reporter_ip_address":"server_ip"}} [response] => Array ( [code] => 200 [message] => OK ) [cookies] => Array ( ) [filename] => [http_response] => WP_HTTP_Requests_Response Object ( [response:protected] => Requests_Response Object ( [body] => Warning: json_decode() expects parameter 1 to be string, array given in /home/customer/www/zerospam.org/public_html/wp-content/plugins/zero-spam-store/core/class-api.php on line 182 {"status":200,"response":"success","body_response":{"report_type":"email_address","report_module":"registration","report_failed":"blocked_email_domain","email_details":{"names":["inspector",""]},"report_key":"[email protected]","reporter_email":"my_mail","app_key":"my_domain","app_type":"wordpress","app_details":{"app_version":"6.0.2","app_type_version":"5.4.3","app_language":"de-de","app_email":"my_mail","app_name":"page_title","app_desc":"page_subheader"},"reporter_ip_address":"server_ip"}} [raw] => HTTP/1.1 200 OK Server: nginx Date: Sat, 08 Oct 2022 12:55:47 GMT Content-Type: application/json; charset=UTF-8 Transfer-Encoding: chunked Connection: close Vary: Accept-Encoding X-Robots-Tag: noindex Link: ; rel="https://api.w.org/" X-Content-Type-Options: nosniff Access-Control-Expose-Headers: X-WP-Total, X-WP-TotalPages, Link Access-Control-Allow-Headers: Authorization, X-WP-Nonce, Content-Disposition, Content-MD5, Content-Type Allow: POST X-Httpd-Modphp: 1 X-CDN-C: static Content-Encoding: gzip X-SG-CDN: 1 X-Proxy-Cache-Info: DT:1 Host-Header: 8441280b0c35cbc1147f8ba998a563a7 Warning: json_decode() expects parameter 1 to be string, array given in /home/customer/www/zerospam.org/public_html/wp-content/plugins/zero-spam-store/core/class-api.php on line 182 {"status":200,"response":"success","body_response":{"report_type":"email_address","report_module":"registration","report_failed":"blocked_email_domain","email_details":{"names":["inspector",""]},"report_key":"[email protected]","reporter_email":"my_mail","app_key":"page_domain","app_type":"wordpress","app_details":{"app_version":"6.0.2","app_type_version":"5.4.3","app_language":"de-de","app_email":"my_mail","app_name":"page_title","app_desc":"page_subheader"},"reporter_ip_address":"server_ip"}} [headers] => Requests_Response_Headers Object ( [data:protected] => Array ( [server] => Array ( [0] => nginx ) [date] => Array ( [0] => Sat, 08 Oct 2022 12:55:47 GMT ) [content-type] => Array ( [0] => application/json; charset=UTF-8 ) [vary] => Array ( [0] => Accept-Encoding ) [x-robots-tag] => Array ( [0] => noindex ) [link] => Array ( [0] => ; rel="https://api.w.org/" ) [x-content-type-options] => Array ( [0] => nosniff ) [access-control-expose-headers] => Array ( [0] => X-WP-Total, X-WP-TotalPages, Link ) [access-control-allow-headers] => Array ( [0] => Authorization, X-WP-Nonce, Content-Disposition, Content-MD5, Content-Type ) [allow] => Array ( [0] => POST ) [x-httpd-modphp] => Array ( [0] => 1 ) [x-cdn-c] => Array ( [0] => static ) [content-encoding] => Array ( [0] => gzip ) [x-sg-cdn] => Array ( [0] => 1 ) [x-proxy-cache-info] => Array ( [0] => DT:1 ) [host-header] => Array ( [0] => 8441280b0ca563a7 ) ) ) [status_code] => 200 [protocol_version] => 1.1 [success] => 1 [redirects] => 0 [url] => https://www.zerospam.org/wp-json/v5.4/report/ [history] => Array ( ) [cookies] => Requests_Cookie_Jar Object ( [cookies:protected] => Array ( ) ) ) [filename:protected] => [data] => [headers] => [status] => ) )
