 * Hello, I made a new site and tested this plug in to check if it’s better than
   fast cgi. Unfortunately, page speed insights says that my site is using deprecated
   API. When I was using fast cgi, there’s no such error. What should I do?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fdeprecated-api-2%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@harmonyous](https://wordpress.org/support/users/harmonyous/),
   I have looked
   at isssue and ran your website in Google PSI. I honestly have no idea what’s 
   causing that cause generally if Google PSI tool shows deprecated API, it also
   shows exactly which script is using deprecated API and what deprecated API is
   being used.
 * But unfortunately every time I have tested it did not show the name of the script
   or the API name for which it is throwing the error.
 * I have also checked browser console to see if there is any info about deprecated
   API but unfortunately nothing is there as well.
 * Even running Lighthouse at the browser level did not throw that message. So, 
   I am not sure what’s causing this. Maybe it’s a bug in Google PSI tool, not sure.
   But I think you can definitely ignore it.

 * Hi [@isaumya](https://wordpress.org/support/users/isaumya/),
   Yeah, only google
   psi has that kind of message. I tried all other checker I can find online there
   no message about api at all.Also tried deactivating all my plugins aside from
   this one but it didn’t work. However, once I deactivated this plugin, it will
   no longer show up. I thought you should be able to find out what’s the problem
   since I only get that error message(?) upon activating this plugin.In any case,
   I think the minus 8 pts on “Best Practices” score is negligible compared to the
   positive effect this plugin brings.Thanks for checking it out.

 * Hi [@harmonyous](https://wordpress.org/support/users/harmonyous/),
   The wired 
   thing is that I’ve also run PSI on many other websites that also uses this plugin
   and I have not seen this issue for any of those sites. Somehow, it’s only there
   on your website.
 * Just to know are you using the option “Remove Cache Buster Query Param” option
   inside the plugin settings > other tab? If not. Try it out. Check the implementation
   guide and add the Cache Rules no. 1-3.
 * Then check again.

 * I also have openlitespeed sites and an old LAMP site that are using this plugin
   and I never had any problem. I tried using lemp for this one and I got this error
   for some reason.
   Tried cache buster and it didn’t work. I guess google hates 
   my new set up.
 * Thanks for checking this out. I don’t think it’s this plugin’s fault.
