Is er iemand die weet wat de oorzaak kan zijn voor het blokkeren van text/event-stream request?
In WordPress gebruik ik een plugin om demo data te importeren, maar krijg ik de foutmelding:
Undefined index: demo in ...\soo-demo-importer\soo-demo-importer.php on line 205
De ontwikkelaar van de template zegt het volgende:
The importer uses event-stream events to import demo content. But it seems your server doesn't support them well.
de volgende PHP instellingen heb ik al gewijzigd:
display_errors=on
error_reporting=22519
max_execution_time=40000
max_file_uploads=2000
max_input_time=40000
max_input_vars=2000
memory_limit=512M
open_basedir=""
post_max_size=100M
upload_max_filesize=100M
error_log="C:\Inetpub\vhosts\s02.unveil.nl\logs\php_errors\test.s02.unveil.nl\php_error.log"
Het script dat de data importeert ziet er als volgt uit:
<?php
/**
