I want to export a survey for import on other website.
When clicking on export I get a blank page, when error reportin on I get these lines:
Warning: require_once(PEAR.php): failed to open stream: No such file or directory in /home/public/sites/domainname/components/com_cjlib/lib/misc/Serializer.php on line 53
Fatal error: require_once(): Failed opening required 'PEAR.php' (include_path='.:/usr/share/php') in /home/public/sites/domainname/components/com_cjlib/lib/misc/Serializer.php on line 53
I have joomla 3.9.24 and CS 5.5.9 and cjlib 3.0.11
How can I solce this error?
Thanks in advance
