wamp cannot load mysqli extension

Question

WAMP installed fine, no problems, BUT...

When going to phpMyAdmin, I get the error from phpMyAdmin as follows:

Cannot load mysqli extension. Please c         


        

Answer 1

I was running WAMP with two PHP versions 1) 5.2.9 and 2) 5.2.13.

As per site requirement i needed to change PHP version to 5.2.9 from 5.2.13. after swapping PHP version, error was "mysqli extension is missing". after debugging long time i get to know it was due to wrong "extension_dir" path in php.ini file.

So i changed its value:

Old: "extension_dir" c:/wamp/bin/php/php5.2.13/ext/

New: "extension_dir" c:/wamp/bin/php/php5.2.9/ext/

Restarted All services in wamp server, then it's fixed.
