Hi sandip tawre,
Thank you for posting this error in the forum, me too I have the same error.
I would like to know where in the file index.php did you place the
ob_clean ()
ob_start () ????
or else can you post your index.php on this forum in case other people will have errors of this type
Thank you very much

Hi,
some users are facing this error on 3.5.
Can this be related to MDL-36652 and non-ascii characters on course names?

Whenever flexible_table is being used for exporting data the page MUST NOT print standard header or footer (or anything else for that matter). The only thing that should be executed is table setup and out.
So either a custom theme is used that messes this or the code itself is incorrect. If any of you uses some custom theme try with some stock theme just for the sake of testing.

Hi,
did the problem appear with all the export ? I mean if you do it on another course did you have the same error ?
Because, in fact, it seems to have special character in the course title (has it already remarked).
