Decided to create an exact copy of the live site on the local testing server and then carry out the update on this to see how it operates and see if any problems arise before updating the live site.
Got the testing server set up, database connection etc and copied all the live site folders to the testing server.
Exported the database from the live server and imported into the localhost.
Got a couple of problems, the site displays on the localhost but with a few problems
1. Links to the menu items are other links are not correct, tried adjusting $WA_localRoot = "/"; and $WA_remoteRoot = "/"; in menu.php
Could only get the menu to work with $WA_localRoot = "foldername/"; and $WA_remoteRoot = ""; but this gives the error message below
Warning: strpos(): Empty delimiter in C:\xampp\htdocs\famautest\CSSMenuWriter\cssmw\menu.php on line 10
2. None of the database images are displayed, all the text is correct but no database images. I presume I didn't export the database properly, what should the export settings be for phpmyadmin in xampp? Or maybe this is a links problem?
