I’ve got a MAMP (version 6.3) localhost using Apache running on a Mac Mini locally and i am in final testing before publishing a new plugin that i’ve created. I popped my plugin into my plugins directory (as i will when i go into production) and suddenly, I am unable to access wp-admin to look at WordPress (as in ‘localhost:8888/wp-admin). Localhost access works just fine (as in ‘localhost:8888’), but when attempting to enter wp-admin, the page fails to be served up with the following messages:

"This site can’t provide a secure connection
localhost sent an invalid response.
ERR_SSL_PROTOCOL_ERROR"

I cannot find ANY information that will help me find a solution. There is nothing in the Apache logs at all. I’ve got debugging set up and running on my site and there’s nothing in there at all. I literally have NO idea how to proceed in finding the problem. I get the same messages in either Chrome or Safari.

I’ve searched this error and it seems it could be a few things, but the source seems to be a bad certificate or something. If so, i don’t know how to correct that condition. IF my understanding is correct, localhost doesn’t even require SSL (?), so even the "ERR_SSL_PROTOCOL_ERROR" is confusing.

Another suggestion that i’ve found is to disable your plugins folder by renaming it to essentially invalidate ALL plugins. I’ve tried that as well, no change in the error message that i am receiving.

Can anyone provide any concrete steps for how to resolve this so that i can get into the wp-admin facility on localhost? I admit that i know "not much" about certificates and SSL and the like. I literally don’t know where to start.
thanks!

  1. request via http, something like this

    http://localhost:8888/wp-admin

  2. open your wp-config.php file and add this online

    define('FORCE_SSL_ADMIN', false );
    

    save the wp-config.php file. You can add just above this line

    /* That’s all, stop editing! Happy publishing. */

    Now try opening your localhost this should work.
