I love Reftagger and in all the years I have been using it, this is the first time I have seen this problem.
I have a reference on my blog to Psalm 25:14 (The secret of the Lord is with those who fear Him). When I roll over it, it gives Psalm 25:10 (Who is this King of Glory?).
I'm using Firefox 60.0.1 (64-bit) and Wordpress 4.9.6 hosted on my own server.
Any ideas as to why this is happeniing? This is the first verse I have ever seen this happen with...
