Hi Tanja,
Thanks for your reply.
To clarify: there is no request to any external resource when clicking the sorting arrows. The functionality uses the same Joomla core behavior to reorder the table items via an AJAX request to the backend.
One thing I noticed during testing is that the pagination limit in your view is set to 500 items, which is quite high. I attempted to lower the limit and also tried changing the sort order using different columns, but in all cases, I consistently received the same 423 Locked error.
This strongly indicates that the issue is not specific to the sorting arrows themselves, but rather to how the server handles these types of requests — possibly due to a server-side security module (like ModSecurity) or a WebDAV-related configuration. These restrictions might only be triggered under certain conditions, such as the number of items or specific request patterns, which could explain why it doesn’t happen in other parts of the Joomla backend.
I recommend contacting your hosting provider and sharing the exact error message. You can also mention that this may be related to ModSecurity or WebDAV rules being too strict, and ask them to check the server logs to identify what is blocking the request.
Let me know if you’d like help drafting a message to your host or need anything else.
Kind regards,
Lefteris
