seems like a lot of people started having the same problem at the same time. Plugin was working fine for several months and now stops to work out of the sudden. No changes made to wordpress, not even page updates, ZERO interaction on admin part and then out of the blue – error message.
What do you think could be a culprit here? PHP update on the servers? I have this issue on two different hosting environments – 1and1 and godaddy – different wordpress versions, different contact form 7 versions, different wordpress themes etc…
Takayuki – this doesn’t work. It stopped working on two different websites, one hosted on 1and1 and second hosted with godaddy.com – do you still think it is a problem with hosting?
same problem here… started yesterday the 3rd of March
