LiteSpeed Cache Image Optimization

Can you post the full error here? It should be two hash strings within your ....

Thank you for the quick response.

The full error is shown below (hash changes every time I try to connect).

SAPI Error hash does not match: xWrVVbJlfEJHuAtv

To my understanding this is only one hashcode.

Can you do it again and paste the new error now?

Thats fine even it changed. Its supposed to change each time.

The new message is the one shown below:

SAPI Error hash does not match: ClientCB[] Server[ef4zzkWQ16aIQveZ]

Please turn on debug log and send a request again. After you send a request there should be a callback log. Can you paste it here?

Hello, I have enabled “Advanced” debug level also. Below are the results:

This is not callback log. callback log is some like :

11/07/17 12:00:05.425 [192.168.0.54:47568 1 qWJ] Query String: litespeed_callback=1

Please paste it in https://gist.github.com/

Where can I find the callback log?

Hello,

I managed to pinpoint the cause of this issue. There seems to be incompatibility with CloudFlare.

I disabled CloudFlare on my site and the plugin worked.

Please keep that in mind so as to fix any CloudFlare related incompatibilities in future versions since many sites use their service.

Hi kioub,

Thanks your information. I have a server with CloudFlare to run image optimize success , so not sure how to reproduce it.
Here is my debug log:

yX0] Query String: litespeed_callback=1
yX0] SAPI __callback hash check 6sAXbd660ZtxnbJx: passed
yX0] LSCWP_CTRL: sapi_passive_callback
yX0] LSCWP_CTRL verified: 'sapi_passive_callback'
yX0] Router parsed type: request_callback
yX0] SAPI __callback request hash: 6sAXbd660ZtxnbJx

We can improve or debug if you can share failed callback log from debug log.
Also, do you set any firewall settings from CloudFlare? Do you use Pro plan?

Best,
Eric

I have the default firewall settings (Medium) on CloudFlare, and no I do not use a PRO plan, I am on the free site plan.

Looking forward to your feedback.

Best,
Byron

Hi Byron,

I still not found any litespeed_callback from your log. Can you try again?
or something like SAPI __callback hash check xxxx: failed

You can enable Debug log for Admin only to get error log easier.

Thanks.
Eric

Hello,

No matter how many times I try, there is no log entry marked as “callback” recorded in the debug.log file, that is why you cannot find it.

All it gets recorded is what I posted on my last message. I have enabled debug log from the plugin setting page and set debug level to advanced. Everything else is set to default.

Looking forward to your feedback.

Not so sure is there any settings will bypass Query String? like from CloudFlare?

I do not think so, the caching level is at “Standard” setting. Everything else is pretty much at default values for the free site plan. The main configuration there is that I force redirection to HTTPS through CloudFlare using its “Flexible” HTTPS option.

The only time I see the litespeed_callback literal in the debug log file is when I Pause CloudFlare for my site. When I resume its operation the logs are as I have posted above.
