Hello,
Thank you for the reply. I’ve checked the plugin which was most likely to cause this error and I was right – it was https://wp-rocket.me/ . I did not disable it completely but only removed the features that were optimizing js files and adding cache for mobile devices and that fixed it.
Thanks again!
I have a Version 6.2.05 on website http://www.adisfaction.de/ – I’ve seen in the versioning details that some sort of email problems have been resolved but clearly not all of them. Try typing in my email address moda@newmedia.agency to send an offline message and you’ll see the error message
Hey Patrick,
Thanks for this find. I’m just wondering if there’s any hook so I can make the change without altering the plugin files so I can update it in the future?..
