My WP version = 5.1.1
\nMy PHP version = 5.2.4<\/p>\n
This isn’t really an exec-php problem. PHP opening tags are getting munged.<\/p>\n
A recent update to WordPress caused this problem – not sure which version.<\/p>\n
In a multi-post page view of posts that include the <!–more–> tag, the opening tag for PHP was getting corrupted with an added space between < and ?php. If you viewed the offending post by itself, the error would go away.<\/p>\n
There’s probably a more elegant way to fix this, but here’s my solution:<\/p>\n
Edit:<\/strong> wp-includes\/formatting.php file
\nAfter line 2558:<\/strong> $newtext = str_replace( ‘< !–‘, ‘< !–‘, $newtext );
\nAdd:<\/strong> $newtext = str_replace(‘< ?php’,'<?php’,$newtext);<\/p>\n","protected":false},"template":"","class_list":["post-11510622","topic","type-topic","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/11510622","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":1,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/11510622\/revisions"}],"predecessor-version":[{"id":11510646,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/11510622\/revisions\/11510646"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=11510622"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
