Ok! I did a lot of testing and here is where the problem comes from : <!-- #include file="../Includes/sec4.inc" -->

 

that line of code is in the database and I deleted it and just put a name: Test HTML instead in the same field and run the edit and click a section name from the codes drop down and Test HTML got put in the editor, so it must me something wrong with <!-- #include file="../Includes/sec4.inc" -->   Any help appreciated on this!!!
