My wife just experienced the same problem on her site. She has been using Debian to host wordpress for a long time and it has maintained the installation of php5 through at least three major releases of Debian even though it appears the php package now (under stretch) refers to php7.
Deleting the type in the signature appears to have fixed the problem. Thanks.
I have no experience with php so am curious. Is there a fair chance that simply installing php7 will “Just Work (TM)”? I know you cannot vouch for other plugins, but all things being equal, is it worth giving it a shot?
Edit: this is what appears to be installed with regard to php:
$ dpkg-query -W | grep php
libapache2-mod-php5 5.6.33+dfsg-0+deb8u1
php5 5.6.33+dfsg-0+deb8u1
php5-cli 5.6.33+dfsg-0+deb8u1
php5-common 5.6.33+dfsg-0+deb8u1
php5-curl 5.6.33+dfsg-0+deb8u1
php5-gd 5.6.33+dfsg-0+deb8u1
php5-json 1.3.6-1
php5-mysql 5.6.33+dfsg-0+deb8u1
