Quick update: it doesn’t happen in every post. Some posts work ok.
This is what I see in 3 lines when it doesn’t work:
Share (just this word)
+ (plus sign)

Solved it! I downloaded a fresh config file from WordPress.org, retyped all login and DB data and replaced the one in my site.
Before that, I couldn’t identify any space or ^M character using notepad or notepad++. But, anyway, it’s solved 🙂
Thanks.
I have the same exact problem. Curiously, it is happening using Godaddy after I migrated my website from Windows to Linux.
