After installing corporex_quickstart_j3_v2.2 the front and back end of the website simply show a white page with the text "error". After the Joomla installer ran, I had a warning that the configuration file was not installed and that I would need to install one. It even gave me the file to copy and paste as the configuration.php file. After adding the configuration file is when I got the white "error" page. If I change the htaccess.txt to .htaccess, then I get a 500 Internal Server error.
To track down the real error, I added error reporting line of code to the index page and see 10 deprecated errors on .../libraries/vendor/joomla/string/src/phputf8/ord.php lines 23, 28, 34, 38, 45, 49, 58 62, 71, 81, and one Error: Failed to start application: syntax error, unexpected 'class' (TCLASS), expecting identifier (TSTRING).
Would re-installing the quickstart file be best? Is there a fix for this?
