Ray, per our conversation, I deleted the MySQLi extension, removed the data bridge extension, and reinstalled the data bridge extension (v. 1.2.4). Now I'm getting the following errors when launching Dreamweaver. See attachments. They are in the order in which they appear.
Also, all of my MySQLi server behaviors have disappeared since removing the MySQLi extension, and the option to create a MySQLi connection is also gone in the Database panel. WTH?
On closer inspection, ALL of my WebAssist extension have disappeared! :/
This morning, March 13th, I renamed my DW configuration folder, so it created a new one, I removed my data bridge and design extender extensions, and then reinstalled them. I now have a WebAssist menu item again. However, I still have no MySQLi server behaviors, or any other MySQLi options.
