When I go to component / JCE I get this error message for one site I have:
Fatal error: require_once(): Failed opening required '/home/httpd/vhosts/http://praxis-margulies.ch/httpsdocs/administrator/includes/toolbar.php' (include_path='.:/usr/share/pear:/usr/share/php') in /home/httpd/vhosts/http://praxis-margulies.ch/httpsdocs/administrator/components/com_jce/controller.php on line 131
For all my other sites I get a blank page, no access.
What is important to know: I get the same fatal error message for this one site I have, even after manually installing the latest version 2636. But on my other sites where I got first a blank page, after installing manually the files of the latest version, the access to JCE Administration is again possible/all ok/no blank page no more.
What could be the matter with the site of the fatal error message?
