    Hello, I have a problem with the following error appearing on the site:

    Uncaught (in promise) SyntaxError: Unexpected end of JSON input

    The error appears on the site only when Guest Optimization and Guest Mode are enabled. It looks like a bug in the plugin itself. Could I ask for help in solving this problem? I can provide more details if needed.

    Here are links to screenshots of the error messages and the problematic code snippet:

    How do I make sure of that? Could you elaborate? From error in the console looks like request doesn’t work, but not sure if you referring to that?

    are you have any kind of security plugin ? that is one of the common reason

    and also please check the php error log , it may give something.

    @qtwrk I disabled Wordfence Security, purged all but problem persist. There are no errors in the PHP error log.

    Is there anything else I can do?

    please create a sub-direcotry wordpress site , with nothing else but only LSCWP , and see if sub’s guest.vary.php works or not.

    @qtwrk I just cloned the site to a subdomain, disabled all plugins, did a Purge All, unfortunately the problem is still the same.

    Even after changing the template to the default, the problem still occurs, so I assume that it is the fault of the server configuration. I’m really need help with that issue, because the be Guest Optimization site has a very poor speed test score.

    @qtwrk: Any news on the subject? If not there is no point for me to use this plugin ??
