I have a wordpress site with the civicrm plugin installed. We are still on 4.6, the latest in that branch. But we wanted to try out the latest version, which is 5.16. I cloned the site and in that clone, I installed the zipfile of the new version , using the checklist for the 4.6 upgrades I did before.
When I had finished all steps and try to reload the site, it comes with an error message:
Parse error: syntax error, unexpected ':', expecting '{' in public_html/civicrm-nw/wp-content/plugins/civicrm/civicrm/vendor/league/csv/src/functions.php on line 33
I can enter recovery mode, but I have really no idea what I should do now. Should I try an earlier 5-version, or should I first upgrade to 4.7?
thanks for helping, Ruud
