I guess it is not so much of a problem if it is the same as changing it in phpmyadmin. The fields are not even greyed out, they are just not there.

I also found a topic with the same issue but the guy does not seem to have solved the problem:Ībout setting the site address in WordPress Settings > General: for me this option is not available. Unfortunately I still could not make it work. This topic was modified 8 months, 3 weeks ago by Manon. Thanks in advance for your help on this issue! So to resume: I can access the XAMPP starting page from my phone but not my WordPress site, even under the URL http://manontest (x being the ip address). – if, in addition, I modify the HOST in the wp-config.php file by changing the URL for http://manontest I still can not open the site. By modifying the site URL in localhost/phpmyadmin, switching “localhost” for the IP address of my computer, I am no longer able to open the site, neither on my computer nor on smartphone (in localhost/phpmyadmin wp_options, I modified the URL in both siteurl and home so it looked like http://manontest) – my site’s URL does not work on the phone. – I am able to access the XAMPP dashboard on my phone by typing the IP address of my computer in the browser I am using XAMPP and I would like to view my local site on other devices, especially on a smartphone. After a good search on the Internet and not finding the solution anywhere else, I decided to look for help here 🙂
