Conflict with remove query string functions

Hi @kaiderella

Could you rephrase your question? I don’t quite understand what the issue is.

One thing to note, our plugin does not cache static files (.js, .css) anyway.

Thanks,
Kevin

Dear Kevin,

When I remove query string, Google PageSpeed Insights will report JS files uncached:

If I do not remove query string, the above error will not appear:

This problem does not occur on previous versions. Do you understand?

Thanks so much!

The LiteSpeed Cache plugin does not apply any browser caching rules, so it might be an interference with another plugin.

Could you go to your wp-admin, under LiteSpeed Cache -> Environment Report, could you copy and paste it here? It’ll provide us with information that could prove useful to determining why there was a change.

Thanks,
Kevin

I don’t see anything specifically that will set the browser cache. Could you DEACTIVATE LiteSpeed Cache and see if the browser cache works?

If DEACTIVATING LiteSpeed Cache does not change anything, try adding the following rules to your .htaccess file:

ExpiresByType text/css                  "access plus 1 year"
ExpiresByType application/javascript    "access plus 1 year"

It does not work, even when I add the code below to the .htaccess file:

ExpiresByType text/css                  "access plus 1 year"
ExpiresByType application/javascript    "access plus 1 year"

What happens if you try to downgrade to 1.0.14.1?

If it works, could you send an email to the email listed on the plugin description? Include a link to this thread so we have some context as to what the issue is.

If it does not work, it is likely due to a change in another plugin, and we cannot assist with that.

The issue is not resolved when I downgrade to version 1.0.14.1. It looks like the problem comes from another plugin. Thanks for your helping!
