Hi @matthiaspabst,
Thanks for reaching out.
Looking at the error you reported, this points to a file under the WP Mail SMTP plugin; however, the plugin does not have such a file.
Is it possible that you might have another plugin trying to extend this?
Could you please try uploading a clean copy of the plugin once more. This should help ensure that all the necessary files are included and if the issue persists, this will help identify any plugin behind this error.
I hope this helps!
Hi @matthiaspabst,
Thanks for the follow-up, I checked with the dev team and they confirmed that the reference to smtp-admin-general.min.css is fixed and will be included in the next release.
Thanks again for your patience and for helping us improve the plugin!
