The error is
I see it in http error log and on screen
Parse error : syntax error, unexpected ‘:’, expecting ‘{’ in /var/www/html/admin/libraries/Composer/vendor/symfony/polyfill-php80/bootstrap.php on line 23
Any ideas
So in my httpd side i was using the Redhat software collections. for php so it had a file directing to use php 5.6. wiered the verison upgrade didn’t detect it. but found it.
This was in the /etc/httpd/conf.modules.d path by the way. So something to checkif your a redhat user and use RHCE stuff.
Hope it helps others.
