LimitInternalRecursion

記事を投稿するとかなりの確率でサイトが見えなくなるのを本日確認。

エラーログを見るとこんなのが

どうやらループしているらしいと先生からのお告げあり（.ruも気にはなるんだが）。

LimitInternalRecursion　と　wordpress　で検索すると.htaccessの書き方が悪そうな話もあり、あらためて見直してみた。それが上の図。

当方マルチサイト設定にしているが、その際の設定と通常のパーマリンクの設定が重複してそうな雰囲気。なのでばっさり消してみた（.htaccessを晒すのは汚部屋を開放するようで若干抵抗あるが・・・・・）。

なるほど、設定時には「他の WordPress ルールを置き換えてください」って書いてたっけ。

さて、この記事の投稿でまた落ちるかどうか・・・・・。

追伸：落ちなかったみたい。で、ログをあらためてみてみたら・・・・・
