WampServer

I saw a similar problem someone else was having, but this error is slightly different. I've been using WAMPserver for a little while and went to enable php_exif and encountered an error. I closed WAMPserver, restarted it, and then the box for php_exif was checked but now the icon is yellow, none of my pages load, and I get the following error:

Aestan Tray Menu
Could not execute menu item (internal error)
[Exception] Could not perform service action:
The requested control is not valid for this service

I saw a similar problem addressed except the last line was different, and he was a first time user. Any help with this would be greatly appreciated, I can't find any answers using the forum and google.

What version PHP?

For me it worked on PHP 5.3.0 and older but not 5.3.1. I found that on Windows, php_mbstring is required and php_exif must be loaded after php_mbstring.

Check your php.ini and place php_exif below php_mbstring and that both lines are uncommented.

You said: "Check your php.ini and place php_exif below php_mbstring and that both lines are uncommented "

In my "php.ini", Exif seems below mbstring. This is this short summary:
(...)
extension=php_mbstring.dll
extension=php_exif.dll
(...)

It works now I just put in you proposal order.

Next Possibilities are certainely to install the PHP5.3.0
But the wampserver's link don't work well. I'm sorry but this change not be tested....
