I saw a link in a yellow box on my WP Admin panel informing me to Update Network. When I click is to update the network I get:
Your server may not be able to connect to sites running on it. Error message: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Note that I am not using the https protocol for my site.
(a) should I be concerned?
(b) should I be updating my network sites?
(b.1) if so, is there a manual method?
