Sorry my English is bad.
I did not find (or understand) the answer to my questions on the forum and documentation.
After installing Phoca Guestbook(joomla) on my site, the link opens a blank page with these instructions:
Warning: require_once (HTMLPurifier / error.php) [function.require-once]: failed to open stream: No such file or directory in /xxx/xxx/xx/x/x/xxxx/components/com_phocaguestbook/assets/library / HTMLPurifier / ConfigSchema.php on line 3
Fatal error: require_once () [function.require]: Failed opening required 'HTMLPurifier / error.php' (include_path = '/xxx/xxx/xx/x/x/xxxx/include:.: / Usr/php5/lib / php ') in /xxx/xxx/xx/x/x/xxxx/components/com_phocaguestbook/assets/library/HTMLPurifier/ConfigSchema.php on line 3
I can not find solutions for several days. Thank you for your help with simple sentences if possible.
Denis
