Error message when posting?

[Peter Cresswell]

For some days now I have got this error message when I have made a post.
[phpBB Debug] PHP Warning: in file [ROOT]/vendor/s9e/text-formatter/src/Parser.php on line 186: call_user_func_array() expects parameter 1 to be a valid callback, class 's9e/TextFormatter/Parser/FilterProcessing' not found
[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions.php on line 1836: Cannot modify header information - headers already sent by (output started at [ROOT]/includes/functions.php:3291)

It does post ok but to check this is so, I have to reload the page and go back to the board index then open the thread again.
Does anyone else get this?
As I haven't opened a new thread recently, I might only get the message when I have replied to an existing thread

HI Peter,
I looked into this & thought I had found the cure already. Today I tried something different and I managed to crash the Forum ;0(

I have now got the forum back on line and have just tested with a test post and the error is not coming up. So I may have fixed it or broken it properly this time.

Have Fun

Regards
Paul

Hi Paul
I'll let you know what happens when I click 'Submit' after this!

Posted ok! Except it told me I 'cannot make another post so soon after your last'

Interesting.

I will look later to see its odd behaviour. It could be because I reloaded a backup from yesterday.

I have adjusted accordingly - should be ok now Peter ;0)
