Issue editing/deleting redirects with large number of rules

[Lejars]

Hello,

I am experiencing several problematic behaviors with the Redirection plugin on a website containing around 1900 redirects.

Environment:

• WordPress 6.9.4
• Redirection 5.7.5
• around 1903 active redirects

Issue encountered:

When trying to edit the target of an existing redirect, the plugin sometimes creates a new redirect instead of modifying the existing one.

Example:

• existing redirect:
  /agence/celebrites-tennis-auto/ → /univers-du-sport/

When I attempted to modify the target to:
/univers-autres-sport/

the plugin instead created a new redirect:
/univers-du-sport/ → /univers-autres-sport/

instead of updating the original redirect.

I also encountered a more serious issue:
when trying to delete this incorrect rule afterwards, all redirects were deleted from the plugin (1903 rules).

Fortunately, I was able to restore them by reimporting my CSV file.

During these actions, the plugin was also displaying:
“Load failed”
while:
“REST API: Good”

I would therefore like to know:

• if there is a known issue with large redirect volumes;
• or an AJAX/UI issue that could explain this behavior.

Thank you very much for your help.

1903 rules is quite small in comparison to some other sites, so I don't think that is involved. Do you have any caching plugins on your site?

Hello,

Yes, I currently have a caching plugin installed: WP Fastest Cache.

However, I still experience the same issues even when the cache plugin is completely disabled and uninstalled.

The behaviors I am experiencing are quite serious and reproducible:

• I cannot properly edit an existing redirect target without Redirection creating an additional redirect instead of modifying the existing one;
• when I try to delete a single redirect, all redirects sometimes get deleted instead;
• when importing multiple CSV files and assigning them to a specific group, all redirects are automatically placed into the default “Redirections” group instead of the selected custom group;
• because of this, I am currently forced to:
  1. export all redirects,
  2. modify the CSV manually,
  3. delete all redirects,
  4. then reimport the corrected CSV file.

So at the moment, I cannot reliably manage redirects directly through the plugin interface.

Thank you for your help.

The plugin has had several releases since this was posted. Is it still happening?
