csschopper.com Posted June 13, 2014 Share Posted June 13, 2014 Hi, Open the file /classes/Tools.php, you have a bad character at the begining of this file (first line), it's called BOM: http://en.wikipedia.org/wiki/Byte_order_mark To see it you might have to try different code editing softwares (try Notepad++ first). This is an UTF-8 related issue. Regards Alok Link to comment Share on other sites More sharing options...
NemoPS Posted June 13, 2014 Share Posted June 13, 2014 I believe something is wrong with blocktopmenu.php, what do you have at line 2? Also,enable error reporting as described in my signature Link to comment Share on other sites More sharing options...
csschopper.com Posted June 13, 2014 Share Posted June 13, 2014 sometimes extra spaces also throw such error. So you can check as suggested by Nemo1. Link to comment Share on other sites More sharing options...
