WordPress error with Mailpoet 3.50 update

Hello @gerryshaw,

Thanks for writing. Sorry about the problem with your MailPoet plugin.?Please manually install MailPoet plugin using the previous version: https://downloads.www.ads-software.com/plugin/mailpoet.3.49.1.zip

Here’s a guide to help you:https://kb.mailpoet.com/article/258-re-installing-updating-the-plugin-via-ftp

Let us know if this fixes the problem.

?Thanks,

Thanks for posting a potential solution. I did instal the previous version of Mailpoet but, unfortunately I experienced the exact same problem. Something is causing very high I/O usage on my cpanel and my website struggles to load. I post again the Error that I’m receiving from WordPress. This means nothing to me – but if anyone can decipher what it means and what I need to do, I’d be eternally grateful!!

I’ve deactivated all my plugins (except Mailpoet) and the problem seems to be solved. I then reactivate them one at a time and everything seems fine for a while (no one plugin seems to be causing a problem) but then I log on next day and I have the problem again.
