Hey Carol,
There are many things involved here, but let’s make a plan to understand what’s going on.
Wordpress multisite has no limitation, so that’s not an issue, but there are limitations that come from various other sources… Domains, hardware, and such.
This error most times happen because there was a problem when the site tried to communicate with Wordpress servers.
- First thing to ask is, what are the domains you are using on Local? Some domains might not work because of special characters or something like that.
- Would be good to check if your computer can really handle 7 sites running at the same time. I’m not aware of any limitation from Local for that.
- Install the plugin Health Check (Health Check & Troubleshooting – WordPress plugin | WordPress.org) and see if there’s anything suspicious there, you can send us what’s printed there too.
- There is a weird fix that I found here on the forum that says to switch the server to nginx and back to Apache, if you need help with that let me know. This is the topic:
- Can you provide your Local log and your Apache/nginx log? To get the Apache/nginx log, you go to `~/Local Sites/yourmultisite/logs/apache and nginx. You can send the error.log from both folders if you don’t know what is being used on the environment. To get the Local log follow this:
Let’s follow this path first, and we’ll have more information about the problem to be able to pin point a solution
