This is the error message I receive when I uploaded the plugin to one site.
The uploaded file exceeds the upload_max_filesize directive in php.ini.
Hi there Basheer,
Funny I had to resolve this on one of my sites earlier today 
This is the reference I use:
Article
And in my case, the .htaccess option worked for me…
And BTW - this is not BB specific, you will have this issue with any sizable plugins you try to upload…
Hope you get it sorted…
Dave
Hey Dave,
Thanks for jumping in!
Basheer,
More to what Dave said above, you can also contact your hosting company and have them increase the upload limit for you, if that’s easier.
Ben
thank you . Hosting was supplied by client. I can advise him to increase the size
Awesome! Let us know how it goes!
