ページコピーでフリーズ「Gateway Time-out」
こんにちは。
ご教示いただけましたら幸いです。
バージョンは、 5.7.5.6
管理画面のサイトマップより、ページをコピーし、複製を作成しようとしますと、フリーズします。
10分程放置しておりますと、画面に以下の文字がでている時があります。
「Gateway Time-out
The gateway did not receive a timely response from the upstream server or application.」
その他の操作は問題ありません。他のパソコンでも同じ現象です。
数か月前に実施した時は問題ありませんでした。きっかけも不明です。
どのような原因が考えられますでしょうか。
