Errors with php 8.0

[zetrader]

Hi, with phpbb 3.3.1 or 3.3.2 and php 7.4 this extension (i use the latest version 0.3.4) works fine, but with php 8.0 i have some errors.
When i go on a topic or post, i get those errors at the top of the page :

[phpBB Debug] PHP Warning: in file [ROOT]/ext/tas2580/seourls/event/listener.php on line 439: Undefined array key "post_id"

[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions.php on line 4130: Cannot modify header information - headers already sent by (output started at [ROOT]/includes/functions.php:3009)

Any idea to fix this?

Edit : I tried phpbb 3.3.2 with php 7.4 and 8.0 when i disable this extension, it works fine in both cases.

Thanks,

Pierre
