Would you please share your report number so we can take a look at your settings? Go to LiteSpeed Cache > Report, press the Send to LiteSpeed button, and then come back here and post the report number. Thanks! Hi Lisa Thanks for the reply. I got this message on gtmetrix & pingdom. Report number: AUTBSRJN Anyone know if i can ask elsewhere? @lclarke did you see my message? Hello Woober, We are looking in to this and we will inform you here when we have more information. @tishu sounds good. thanks a lot Hi, @woober One question: which resources was pingdom complaining about? If the resources are external (like Facebook, or Google, etc.), theres nothing that you can do about a missing cache validator for them. Hi @lclarke Its a bunch of internal css/js files (these i would like to have fixed) and one external Hi, @woober Weve narrowed down the problem and we think that your ETag headers are not set correctly. That is a server-level setting, and actually is not related to the LSCWP plugin. If you are not sure how to fix the ETag headers, you can create a ticket through our client area or by sending email to support@litespeedtech.com. Someone from the server tech support team can help you out with that. Cheers! Reason: Fixed email address @lclarke Thanks a lot for that. I will see if my host can fix it first. Our pleasure! Happy caching One more thing. Do this normally have any influence on how fast the whole page is loaded? Sure, if it means that those files cant be cached.
