[Resolved] Subscribe2 Fatal error after 8.9 upgrade
Installed 8.9 version. when I add a new post, I get this error:
Fatal error: Call to undefined function mb_encode_mimeheader() in /home/peiwebs/public_html/peicurling.com/wp-content/plugins/subscribe2/classes/class-s2-core.php on line 354
I tried deleting the plugin (after saving my subscriber list) and re-installing, but I still get the same error.
I note the following in changelog.txt – looks like a call to this was just added:
* Use mb_encode_mimeheader on email sender name – thanks to xl32
