Got that error today. Thanks for pointer as I was coming here to report same issue.
Never saw it before so has to be influenced by new WordPress release as I haven’t changed my maintenance page settings in a year. I also don’t use the subscription form where this bug is located.
I followed your advice and looked in the field and to my shock/horror found over 500,000 slashes in my field.
How on earth did that get there????
Same problem here, any fix ?
@zerrogh
The temp fix (aka without plugin author updates) is to:
1. goto the plugin configuration > Email settings page.
2. locate the “message subscribed field” at bottom right of page.
3. completely replace field contents with a new “Thanks for subscribing” message
I suggest using the TAB key to move between form fields as this allows you to select ALL the field contents in one easy step.
In my case I has over 500000 slashes and holding down [DELETE] to remove a character at a time wasn’t even making a dint.

@snaphappyme Great idea!
That seems to be working for me.
Not sure if it has to do with other/third-party plugins, but so far I’ve encountered that same issue on multiple WP installations that I manage.
Normally I would just be deleting the slashes ever so often. Didnt even think about replacing the message. 🙂
I did a bit of poking around the code of the plugin.
This plugin is pretty benign with its handling of the form field content so I don’t think it is a plugin logic error. I think a dependency library or PHP core function used by the author has changed and triggered the bug.
I suspect it has to do with the PHP strip_tags function which is used to ‘cleanse’ or treat the field before posting the value to the database.
Perhaps the handling of a pre-existing ‘slash\’ in the default string is being handled differently now with the latest PHP code updates.
Nonetheless it is a bug. But as we know a way around it we can at least keep using the plugin safely.
Hi, thank you for reporting this bug! It’s been fixed in the new version which will be available in a few days.
