Cannot modify header information error message
 

I installed the latest version of x-cart - v.3.4.3, and I am getting an error that reads:

I cleared out the entire directory and did a fresh install, used a completely new DB, and as soon as I finish changing some general settings I get this error. I tried replacing config.php, but that did not solve the problem. Can anyone help me with this?

Thanks so much!

see if you have blank spaces at the end of your config.php file and if so remove them

There are no blank spaces at the end of config.php. Everything works fine for about 5 min, and then I will move to a different config page (it's never the same one every time), and I will suddenly get the error.

reinstall it
 

make sure u actually uploaded all the files...i once uploaded it and missed the entire modules folder...and wondered why it didnt work, so try to upload it again. I had to upload mine over 10 times before I realized it was my host's fault it wasnt working...so I switched hosts.

I did open my config.php in dreamweaver and there was an extra blank line at the end i deleted...but i dont know if it affected anything. I am also using 3.4.3 and once I figured out the linkpoint issue I have ZERO issues or problems with it at all.

Yay, this fix worked for me :)
