Hi evis, it was the frontend of the website – where I was blocked!
I have a feeling this is due to a combination of two plugins I was using on that application.
Apologies for the “harsh” review, this was a scary place to be and cost a couple of hours getting out of trouble.
All the best,
James
Go to file :
/wp-content/plugins/configure-smtp/configure-smtp.php
On line 171 locate this :
public function options_page_description() {
and swap for this :
public function options_page_description( $localized_heading_text = '' ) {
Hope this helps and not it’s too late, just fixed it on my install and thought I’d share!
