Upgrade instructions look pretty easy. We have no apps, no templates or addons... we don't do anything fancy... straight out of the box. We started with 2.8.15 but upgraded to 2.8.32 in the past. Did the backups. Testing locally so domain is 127.0.0.1. Downloaded perch 3.1.4. Replaced perch/core. Deleted perch/addons/plugins/editors/markitup
Executed 127.0.0.1/perch which picked up that it was an upgrade. Continued. OK. We note that the table names still have a prefix of perch2!
Went to 127.0.0.1 and we got 'Fatal error: Cannot redeclare perch_page_modified() (previously declared in /var/www/html/perch-en/core/apps/content/runtime.php:601) in /var/www/html/perch-en/core/apps/content/runtime.php on line 601'
Any ideas would be appreciated.
