I am getting the following error on 3 browsers (Chrome FF Edge). I have read the other threads on this error and tried the suggested fixes with no luck.
“Unknown error. Failed to load the form. Please check your internet connection, contact your web site administrator, or try again later.”
Updated SiteOrigin plugins. Researched error on forum. Disabled plugins and cleared cache. Tested. Same error. Reactivated plugins. Installed Really Simple SSL per forum. No mixed content issues evident. No joy. Checked Wordfence security. Removed old plugins. Ran new scan. No change.
My colleague does not see the error in another city using a Mac.
