SQL error when I try ti recompile all languages

Found error in the file '/home/nguoimau/public_html/mysite.com/inc/classes/BxDolInstaller.php' at line 660.
Called 'db_res' function with erroneous argument #0.

I can tell you exactly why it is tripping up, it is the single quote in the It's Complicated.  Single quotes has caused problems in Dolphin before.

Quick fix, change it to "It is Complicated"

Thank you, Geek Girl.

I cannot find any It's Complicated in the mentioned file (at line 660, the _FieldValues_ is not "it's complicated").

No, you don't understand, the value is not in that file, it is in the keys.  A query is form in the BxDolInstaller and that query is ill formed due to the single quote.  This is a bug and needs to be addressed.  Probably to fix will mean a database edit to change the key.  If you are unsure about doing database edits, then send me a PM.  Of course always do a database backup before manually editing the database.

Oh, just say that you are at 7.1.4 so this might have already been fixed.  By the way, if you are intending to stay at 7.1 line I would suggest upgrading to 7.1.6 to pick up some bugs and security fixes and then there is the security issue stated during the 7.2 line that can be manually done to the 7.1 line.

Actually, you may be able to change the value for that Field Caption by going to your Profile Builder.  However, it may throw an error there as well when it tries to load the key into the builder.
