Biggest opportunity: Swap “error page”, “logging” and “redirect” for “error 404”, “redirect 404” and “404 page”. “error page” isn't earning its slot: you're not in the first 24 results for its own search. “error 404” sits at #8 untagged, close enough for a declared tag to move it up. “logging” isn't earning its slot: you're not in the first 24 results for its own search. “redirect 404” sits at #9 untagged, close enough for a declared tag to move it up. “redirect” isn't earning its slot: you're not in the first 24 results for its own search. “404 page” sits at #10 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

2.2%

of downloads still active

At least 7K of 316.7K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,767 plugins.

Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

This plugin shipped 19 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

    Thank you so much for this brilliant plugin. I am not technically confident, cannot do much by way of coding and get overwhelmed with geek speak. I downloaded this plugin after trying (and failing with) another, and within 10 minutes had my custom 404 page up and running. This has saved me time, energy and stress. Thank you so much. I have just donated something small too to support you in your work and creativity.

    На мой взгляд, это лучшее и простое дополнение для перенаправления! Перенаправляет даже с «закрытой страницы» ?author=1 что другие подобные дополнения делать не могут. Молодец.

    This plugin was working great for us until we adjust the settings to start logging the 404 pages. Then, the custom page we selected in WordPress for the 404 to route to stops working. Is this a known bug?
