From the various posts in the previous topic entitled "Broken", I was able to figure out exactly what to do. since someone had complained that they couldn't figure it out, i'm being super explicit.
Per maex sworcik the procedure is below:
to fix the "ADD TAG" problem change: $neuertag = "INSERT INTO$dfr_tabelle(SCHEMA, TAG, FONTSIZE) VALUES ('$schema', '$tag', 'px')"; in "../wp-content/plugins/dynamic-font-replacement-4wp/admin/listings.php" to $neuertag = "INSERT INTO$dfr_tabelle('SCHEMA','TAG','FONTSIZE') VALUES ('$schema', '$tag', 'px')";
however, per Joseph Fneisz, you also need to do this:
change all of the single quotes in the following:
to backticks. because of the way this forum is setup, it seems to be impossible to display a backtick so that you can copy & paste it. so look at the php in the file, and find the funny backtick marks surrounding the '$dfr_tabelle' immediately preceding, and copy & paste those.
