WP Pages connection lost

Hello,

I’ve been having problems every time I try updating/posting a page. Whenever I try to update/post a page I get the error “Connection lost. Saving has been disabled until you’re reconnected. We’re backing up this post in your browser, just in case.”

The page content still gets updated when I view or preview it, however other settings like SEO are always lost.

Note: This is definitely not a browser issue as posts have been working fine & this has occurred over the past few versions of WP.

I’ve tried searching through the forums for similar issue but couldn’t find a solution. Please advise.

Best,
egyft
