your hosting provider must have upgraded php in server.

messages these should written php error log , not displayed. can fixed in php settings. however, can rid of messages changing error reporting option in global configuration 'system default' 'none'.

fatal error: class 'jparameter' not found in /home/advacoll/public_html/plugins/system/wibiya/wibiya.php on line 26

this php fatal error occurs in plugin have installed. class looking defined in /libraries/joomla/html/parameter.php file must corrupted or gone missing. can find copy in joomla installation archive point release of joomla 2.5 running. copy file server , error should disappear.
