Ok I've searched for DAYS in search for a solution to this.
I've tried EVERY .htaccess addtion (even though i DO NOT HAVE the file) I've created it and added the coding everyone has suggested.
Downloaded multiple plugins
Tried every possible trick that has come up by searching and I'm VERY fed up with the issue.
I'm having no problems uploading smaller sized files however as soon as I try to upload say a 1.8mb image I get the famous HTTP Error.
I need this fixed asappppp
