I have installed the latest version of the template OnePage 2.7 and SP Page Builder 3.7.2 using Joomla 3.9.16 for Linux. I am having problems with opening the front page editor. It worked initially but when I edited the blog module it froze. After rebooting and clearing the cache, the front end editor will not open. At first there was an error message that a joomla file xxx/renderer/head.php was missing. I followed forum advice that this file is no longer in Joomla 3.8 and commented out line 28 in the templates/shaper-onepage/error.php that starts with "require_once () " . Now when trying to start front page editor there is a message "syntax error unexpected '<', expecting end of file: object of class Std Class count not be converted to string."
I have used the charity template in the past and had no trouble but this template is giving a lot of problems. Any advice appreciated.
