Invalid argument supplied for foreach()

    The plugin displays an error on one of my websites when I view the email log screen:

    Warning: Invalid argument supplied for foreach() in /home/sites/15a/6/656a670f33/public_html/wp-content/plugins/wp-mail-catcher/src/GeneralHelper.php on line 195

    I have 850 emails in the log on this website. I have another website on the same server with only a handful of emails, which doesn’t show this warning.

    I guess it could be an issue with scale? I can’t confirm if it’s having an impact on sending emails, as one hasn’t gone out since I noticed the issue and updated the plugin to the latest version.

    Hi, thanks for the report. You’re not the only one to report this but I haven’t been able to reproduce it. From what I can gather there are certain emails that trigger this. If you can nail down What sort of emails are you logging, are they WooCommerce, Contact Form 7 etc

    Hi, it seems to be that I had 2 items in the list of emails without any data (no to, subject or timestamp). When I deleted one, two of the warnings went away. When I deleted the other, the last 2 warnings went away.

    One of the emails seemed to be triggered by “WP HTML Mail – Email Template Designer” – you can send a test email from their settings page, the blank item in the list was directly before the test email I sent.

    Could it be a case of checking if the log has any data in it, and if not, don’t show it in the list?

    Hi @lukeseager, thanks for the additional info I’ve created a bug ticket in our GitHub tracker so I’ll close the issue here. I’ll look into resolving this for the next update

    No problem, it doesn’t seem to effect emails going out, so not a major problem.
