I installed the plugin code to the page using Inline PHP plugin and got an error at the beginning of the page:
Parse error: syntax error, unexpected $end in /var/www/grawl/data/blog/wp-content/plugins/inline-php/exec_php.php5(4) : eval()'d code on line 1
Parse error: syntax error, unexpected T_ENDIF in /var/www/grawl/data/blog/wp-content/plugins/inline-php/exec_php.php5(4) : eval()'d code on line 1
Although all the works - 4 random deviations are shown at the page bottom.
A list of installed plug-ins you can look at the bottom of the page "О сайте".
