MySQLi extension Activation error
I've recently re-installed Dreamweaver CC 2017 and then re-installed the mySQLi extension. After restarting, I try and input the serial numbers but there is a javascript error window behind (see attached). It seems to be looking for a file that doesn't exist. Everything was working fine with CC 2018 until recently when I started getting errors messages from the mySQLi extension (no tables found, wrong type of connection etc.), so I've uninstalled it and installed CC 2017. Now I can't validate it.
I am using 64 bit Windows 10. I've tried uninstalling, reinstalling and get the same every time.
Thanks,
Mike
