Front-end search Error After Update from 4.22.5

Hi Ernest,

I am facing a weird issue. After the latest, the search stopped working. it is giving an error as attached. I tried clearing the cache and downgrading the WPRocket plugin as they all got updated together, but nothing worked.

I then downgraded ASP to 4.22.5 from my backup and it is working as intended with the updated Cache plugin as well.

So, 4.23 or even 4.23.1 both are throwing the same error as in the screenshot. I did a basic check, admin-ajax is working.

Hi,

This error is caused by an uncleared browser, minify or CDN cache. The older version javascript files (which must be heavily cached), while the response from the server is from the newer release – and the old version of the script can not verify that.
This very rarely happens, as we don’t change the output significantly, but in this case we had to change the response delimiters for compatibility reasons, and the cached script from 4.22.5 and below will throw this exact error for the new server response.

If you clear all layers of cache – including minify, asset, CDN, page, browser etc.. it will resolve the issue for sure.

Hello,

The only thing that I did not clear is the CDN Cache. Will give it a try as well. I hope all goes well.

Hello,

Yup, CDN cache clearing fixed it. Thanks 🙂
