See what the support of my host replied: php extensions. Dll are for use on Windows servers. For we activate this extension, you must recompilarmos Apache and PHP on your dedicated server. . My server is not windows' is linux

Dear amaral,

You can enable this extension on Linux server.

Thanks

On my server will not have to do this procedure. I will not allow this operation, see what the host replied Unfortunately the activation of extension 'exif' can only be done with recompile Apache and PHP. During the rebuild the sites were offline.

Dear amaral,

I am checking this issue now.

I will inform you about it as soon as possible.

Thanks
