Same problem here after updating to the latest version.

Warning: Cannot modify header information – headers already sent by (output started at /home/customer/www/HIDDEN/public_html/wp-content/plugins/wp-rss-aggregator/includes/cron-jobs.php:329) in /home/customer/www/HIDDEN/public_html/wp-includes/functions.php on line 6712

HIDDEN is me just hiding the domain. Happy to share it privately.

I just see, that this topic was marked as resolved???

Up to now, there is no update to the plugin and no public advice how to solve …

Hi @saarfuchs, can you please install the WP Crontrol plugin, then go to the Tools > Cron events > Cron Schedules page (the second tab, not the one that lists the cron jobs) and check whether you see an error there or a schedule in the table that has no value in the “Interval” column?

This issue was fixed in WP RSS Aggregator v4.18.2, so it should not still be happening at this time.

Hi @markzahra,

I followed your advice and installed WP Crontrol 1.11.0. Further I checked the version of WP RSS Aggregator, which is 4.19.2.

On the second tab with the time plan, there are 15 plans: Every of them has got a time intervall.

Here is the list:
wpo_page_cache_preload_continue_interval, 600 (10 Minuten) 10 minutes
ao_ccss, 600 (10 Minuten) Autoptimize CriticalCSS
sbi30mins, 1800 (30 Minuten) Every 30 minutes
webpc_cron, 3600 (1 Stunde) WebP Converter for Media
hourly, 3600 (1 Stunde) Einmal stündlich
twicedaily, 43200 (12 Stunden) Zweimal t?glich
wpo_daily, 86400 (1 Tag) Once Daily
wpo_use_cache_lifespan, 86400 (1 Tag) Same as cache lifespan: 24 hours
daily, 86400 (1 Tag) Einmal t?glich
sbiweekly, 604800 (1 Woche) Weekly
wpo_weekly, 604800 (1 Woche) Once Weekly
weekly, 604800 (1 Woche) Einmal w?chentlich
wpo_fortnightly, 1209600 (2 Wochen) Once Every Fortnight
wpo_monthly, 2592000 (1 Monat) Once Every Month
wpgdprc-monthly, 2635200 (1 Monat) Once a month

In the log file from this day, there are still the messages:
[04-Nov-2021 10:24:02 UTC] PHP Warning: array_flip(): Can only flip string and integer values, entry skipped in /var/www/www.saarfuchs.com/wp-content/plugins/wp-rss-aggregator/includes/cron-jobs.php on line 329

Do you have any other suggestions to check?

Thanks in advance
Joerg
