ob_end_clean(): failed to delete buffer. No buffer to delete

abmanhero

Hi after the last update of AcyMailing plugin on WordPress I get many 524 errors from Cloudflare and in my error log file, I get this error as well.
[28-Oct-2020 06:28:16 UTC] PHP Notice: ob_end_clean(): failed to delete buffer. No buffer to delete in /home/site/domains/domain.com/public_html/subfolder/wp-content/plugins/acymailing/front/controllers/frontstats.php on line 51
Can anyone please help me to fix this problem?

Hi,

You'll find more info about the Cloudflare 524 timeout here: https://support.cloudflare.com/hc/en-us/articles/115003011431-Troubleshooting-Cloudflare-5XX-errors#524error. Please contact Cloudflare or your hoster to find a solution for this.

As for the ob_end_clean(), it's a notice not an error. You can safely ignore it.
