* I have been seeing continual errors in lightspeed error logs:
* ReferenceErrorphp_data is not defined
/wp-content/litespeed/js/6c49f5c3cb9d989815a1b16ca18381a2.
js in ?
* ReferenceErrorCan’t find variable: php_data
/wp-content/litespeed/js/6c49f5c3cb9d989815a1b16ca18381a2.
js in global code
* There are lots of slow queries eg:
LiteSpeed\Img_Optm->img_count()
* ```
SELECT COUNT(*)
FROM wp_posts a
LEFT JOIN wp_postmeta b
ON b.post_id = a.ID
WHERE a.post_type = 'attachment'
AND a.post_status = 'inherit'
AND a.post_mime_type IN ('image/jpeg', 'image/png', 'image/gif')
AND b.meta_key = '_wp_attachment_metadata'
```
* Might site has been having issues going over cpu i/o useage etc since using this
plugin.
* I am not a developer. I am at a loss and this is affecting my site. Please explain
how to fix.

* I’d suggest using a browser’s developer tools, network. See if you’re loading
guest.vary.php okay.

* Hi,
* please provide the report number , you can get it in toolbox -> report -> click“
send to LiteSpeed”
* the slow query is normal , it’s backend image optimization process
* well , you can not expect zero IO or CPU when you doing image optmization in
background …

* I’m still waiting on a reply to my query. I sent the report in.
* There should be no backend image optimisation occurring because this is all turned
off.
* [@splaquet](https://wordpress.org/support/users/splaquet/) i can’t see this code
at all. I’m not sure where to look.

* See my first question.
You can see these in all speed test software and logrocket
software.

* Hi,
* yes, I saw the first post , which makes me wonder which log you referred to ,
because the message itself looks like something from dev tool console would show
* I just tested with GTMetrix, but didn’t see any error message as in your first
post , may I know where exactly can I see it ?
* assuming it’s a JS error from dev tool console , first of all please try disable
all the JS options , purge all , to see if error still shows , if that is gone,
then try to narrow down which option caused and then seek how to deal with it

* I’m not a dev. How do I disable JS options and do you mean for lightspeed only?
* Is the wp-content lightspeed your plugin or lightspeed the hosting caching side?
* Some of that info would have come from query monitor

* Hi,
* it should be in wp-admin -> LiteSpeed Cache -> Page Optimization -> JS options
