If you upload large extensions ( > 2 MB ) to your joomla website running WAMP, you may run into the following error: There was an error uploading this file to the server.

As a default, the maximum size of the database is 2,048 KB. You can change this in WAMP in case you have a large database. Click with the left mouse on the wamp icon in the toolbar. Select PHP and php.ini. Note book will open and search for the following code: upload_max_filesize = 2M and change it to 4 M or 8M and save the file:

 

The error will no longer appear when you upload an extension that is smaller than the max you have set in the php.ini.
