Thread:Talk:MediaWiki/File uploading limit??? (3)

I need to change the maximum upload file size but its not working with me the upload window shows this

Maximum file size: 2 MB (a file on your computer) Permitted file types: png, gif, jpg, jpeg, doc, xls, mpp, pdf, ppt, xlsx, jpg, tiff, odt, odg, ods, odp.

so i need to make the maximum file upload 150MB i edited the following according to the Manuals in the website Manual:Configuring_file_uploads

\xampp\htdocs\mediawiki\LocalSettings.php $wgUploadSizeWarning = 157286400; $wgMaxUploadSize = 157286400;
 * 1) MaxUploadFiles

from the \xampp\htdocs\mediawiki\LocalSettings.php file

and

upload_max_filesize = 150M post_max_size = 150M

from the \xampp\php\php.ini-development file and also in the C:\xampp\php\php.ini-production file i know i am supposed to edit php.ini but these are the php.ini files that i found in the php folder so im not sure if i am editing the right files?

even after making these changes i still get this error Warning: POST Content-Length of 18143113 bytes exceeds the limit of 8388608 bytes in Unknown on line 0

so how can i change the file limit for the upload?

Thanks
