Redirection 500 limit?

There’s a known bug with the plugin where the number of redirects you can store will be limited by the number of inputs PHP is configured to process in a single request. By default PHP will process 1000 inputs, which means the plugin will support 499 redirects. Until a new version of the plugin can be finalized, there are a couple of workarounds:

* Increase the number of inputs PHP will handle. See Ben’s post at the top of this thread for one way to do that: https://ww.wp.xz.cn/support/topic/cannot-enter-more-then-499-entries/
* Use the bulk uploader add-on plugin to upload new redirects in a CSV file https://ww.wp.xz.cn/plugins/simple-301-redirects-addon-bulk-uploader/
