I am very much a beginner and am learning. Please forgive any idiocies
I am at this moment trying to teach myself how to backup and restore a copy of my website between two local PCs on the same intranet.
I have xampp and Joomla 3.4* installed on Computer 1 and 2
I have created a test website (joomla 3.4) on Computer 1. I backed it up using Akeeba I used Filezilla to transfer the backup files it to Computer 2. I used Akeeba extract wizard on my transferred backup files. The extracted files now reside in their own folder (joslmetz) in htdocs.
All messages at all stages so far have been succesful operation.
I then access joslmetz under localhost and Angie kicks in to restore msy files. The message shows as succesful. until I click to see front end website which is last instruction in Angie and then I get a list of notices and warnings (available if interesting) and the final fatal error message attached.
Fatal error: Cannot use Joomla\String\String as String because 'String' is a special class name in C:\xampp\htdocs\joslmetz\libraries\vendor\joomla\registry\src\Format\Json.php on line 12
What do I need to do. *Please note that I have purposefully installed Joomla 3.4 to mirror a friend's website. So that I can take her through the steps she should follow to make site changes in a safe way and upgrade to 3.6. First of course I need to understand myself.
I will appreciate any advice
