Getting error on Restrict Access to Page

On pages where I already have successfully added MySQLi Restrict Access to Page, and I'm trying to add it to a new page, now I'm getting the error:
"In file MySQLiRestrictAccessToPage": InitializeUI is not defined" My WampServer is up and running and the database is connecting.

I've never seen this before. Even if I double-click the Restrict Access server behavior in a page where it previously worked, I get the same error message. Why is this happening?

reset the workspace layout:
go to Window -> Work Space layout -> Reset '<your layout name>'

and Delete the Dreamweaver Cache file from the users configuration folder:
http://www.webassist.com/tutorials/Common-installation-issues

I did both of those things and the error message persists. Next?

Try restarting the computer and deleting the cache file again.

OK, I restarted, deleted the cache file again, and still the error is there.

One question: in my Adobe folder, I have a Dreamweaver CC folder and a Dreamweaver CC 2014 folder. The CC 2014 folder has the later date, but when I look through its Configuration folder, I do not see the cache.dat file. There are 11 other folders inside that Configuration folder and I've looked through each one and don't see it.

However in the DW CC folder, I open the Configuration folder and there the cache.dat file is, at the very bottom of the list. That's the one I'm deleting.

What version of DW are you using? that is the folder you should be looking in, the one that matches the version of DW you are using.

try uninstalling the MySQLi extension from the extension manager, then reinstalling it.

DW CC 13.2 build 6471. I'll try uninstalling MySQLi and see what happens.

Finally, uninstalling and reinstalling MySQLi extension worked. Thank you!
