* Hi There.
* Up until recently the Pingdom Website Speed Test was giving me a Performance
Grade of around 98 for my homepage, but recently this has dropped to 92 and I’m
receiving the following error:
* The following resources are missing a cache validator. Resources that do not
specify a cache validator cannot be refreshed efficiently. Specify a Last-Modified
or ETag header to enable cache validation for the following resources:
* [https://chromasia.com/min/1fc15.js](https://chromasia.com/min/1fc15.js)
[https://chromasia.com/min/38be9.css](https://chromasia.com/min/38be9.css)
[https://chromasia.com/min/415a7.js](https://chromasia.com/min/415a7.js)
* Is it possible I’ve inadvertently changed something to cause this or is it expected
behaviour? I should also add that I’m running my site though a basic cloudflare
account, but get this error even when bypassing the cloudflare cache.
* Many thanks in advance.
* The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmissing-cache-validator-2%2F%3Foutput_format%3Dmd%26view%3Dall&locale=en_US)

* Hi Chromasia,
* We do have `etag` for it, you may want to check is there any rules may un-tag`
etag` from header in .htaccess file.
* Let us know the result of finding the rule.
* Best,
Eric

* I should add that all the other files required for that page, including a couple
of css and js files, don’t have this problem. It’s only the combined css and
js files that have the issue.

* The ability to ‘Load Google Fonts Asynchronously’ in v1.6.3 is a good addition,
and probably makes a significant difference in real world speeds, but it’s added
another file to this issue, i.e. both GTmetrix and the Pingdom Page Speed Tool
report that “The following resources are missing a cache validator.”

* Hi Dave,
* Checked from GT, there are four resources missing a cache validator, but I can
not found any from your htaccess file.
So, there are two possible reasons. 1.`
etag` disabled from LSWS->Server->Configuration->Tuning->File ETag 2. `etag`
disabled from apache configuration, and lsws set yes to `Using Apache Configuration
File`
* Could you contact your hoster to confirm these two items?
* Best,
Eric

* Here’s the reply …
* “Configuration -> Server -> Tuning -> Static File Delivery Optimization -> File
ETag is not set, so it’s the default which is to have iNode, Modified Time and
Size enabled.
* I can’t see FileETag explicitly configured anywhere in the Apache configuration.”
* Do I need to ask for it to be turned on?

* Hi There,
* Is there anything else I should check or try? I’d really like to get this sorted
out if possible.

* Hi Dave,
* So, there is no `FileETag None` in Apache config and `unset etag` in .htaccess.
* I didn’t figure out which reason cause the issue now. Could you please create
a ticket so we can have a further check on it?
* Best,
Eric

* Finding result:
For some reason, routing through Cloudflare strips the eTag.
